Right now you have a good starting point, but it needs some interest.
Just because it is minimal doesnt mean it has to be flat.
Add maybe a paper/wood/light speckles to the background for texture.
The three green sentences do something fun with those, to me it looks like "we arrange the very best weddings in Scotland" pause at the most desirable and romatic venues pause at a cost that makes this experience possible for you. (the spacing is weird, I would make it all one sentence)
The seporator: either lose the drop shadow or make the drop shadow lighter.
Three Pictures: make them all black and white, and maybe when you rollover them they become colored.
Footer: Footer looks really dark compared to the rest of the site, I would lighten it up a bit, and even make it a bit smaller.
I would also add some color to the top, since it seems to be lacking there.
Hi,
You have a good start and clarity of content. Have the following to say however.
Considering that this is a design for a wedding planner, I will try playing with a different font, especially for the headings 'cos verdana is not working well here i think. (Type is header is okay)
Also check your line-height/leading.
Hi Olly, this is a good starting point for your design. It shows good classic minimalistic design elements and has the potential to be really good. Here is what I think will put this design in the right direction:
Reconsider the passage Length. The paragraph area under your tagline is too wide. The visitors of your site are probably not going to spend the time to read it. Try shrinking the width of the paragraph and adding a new element for the newly empty space.
Center the Navigation Bar. If you are going to have a nav bar with links that almost fill the width of the page, then you should center them. If you don't like the way that looks, then try adding another link so that it extends from the left to the right.
Decrease some of the margin the nav bar has from the logo and the slideshow below. Not by a lot, only maybe 5 pixels. It will make that area more connected and maybe increase the focus of your design.
Typography for your site. This is a big concern for your design because it seems as if you haven't put much thought into the fonts that you have used for your design. Reading this article on selecting fonts will help your design, http://designm.ag/resources/on-selecting-typefaces-for-different-passage-lengths/.
Overall, your site has a lot of potential to be great and will want to see how it progresses.
You've got a good start here. I do think you have a lot going in your footer there with a semi-complicated silhouette. Look at going with one of the concepts (the grass, the kissing couple, or the castle) for the footer instead of all three. I've also made some notes on the mockup below.

The Verdana sticks out like a sore thumb here. Maybe you can go with a serif font like Georgia here to tie into the logo.
I think you could get away with using a script font here since this is for decoration. Maybe look at some calligraphy fonts like Jane Austen (overused, IMHO, but effective) or Bickham Script (also overused, but super effective).

I think you could bump this up a font size or two for better legibility.
Quite a nice design. Possibly needs a little more contrast - mostly in the green heading's - which I would make slightly larger and perhaps place them over a background grey/glass fade. I would also change the 'Professional wedding planners in Scotland' tag under the top logo to the same green as the headings - agin to add a little more contrast and distinction. Like the footer! but perhaps the header should have a little more contrast? Generally a good design - just needs a little more contrast and visual distinction of headings and I think it would be excellent! Well done.
The test in the middle of the page just isn't working for the site. Try bringing the 3 images up above the text just below the main image and make the main image a slider - showcasing the other weddings. Next add the shaded bar under the 3 images and then add styled font. Maybe with an uppercase letter at the beginning of the paragraph that is styled and colorful.
I think you are headed in the right direction. Overall the typography of the design needs the most work. See my notes for details. I also think that it looks a little flat and again I have some ideas on that so see my notes. Good work though!

While the center aligned treatment is fine, the choice of typography here needs some help. I'd suggest using a serif font, perhaps closer to what is being used in the logo. I would also suggest trying to work in some sort of flourishes to balance the typography.
The main navigation gets lost and it may simply be that the font can be enlarged, but because you are already limited on space, my suggestion would be to add a background color bar to pull this out. You may be able to tie in the main photography element with this as well.

I definitely think your headers would be better served by using a serif classic font.
Try bumping the body text up a size or two and add some more line spacing to let this copy breathe a bit.
I would also look at adding some sort of very light texture to your background to give the overall layout some depth. This can be very minimal though.
I believe the pictures are correct, couples getting happily married with beautiful landscapes. Now the menu and text information seems to be a little hard to get interested in, the colors of the background and fonts does not work very well. they look wash out and the paragraph in the middle seems boring to ever care to read, break the information a little more, do not worry this is a mistake that I also have done. Use more interesting font types for the titles. maybe change the green line of the middle for a decorative swirl. some examples: http://www.istockphoto.com/filethumbviewapprove/5436644/2/istockphoto_5436644-decorative-elements-vector-illustration-ornament-swirl.jpg
I love the bottom part of the page (just little up a lit bit) and the pictures are beautiful I think your going in the right direction (much better than the original one they have)
definitely for me as you possible audience target I will recommend pastel colors an a swirl or other little elegant detail around the pictures or where you see fit, research for weddings colors and am pretty sure you will find a lot of nice options that will match and enhance what you have in your mind.
it just a matter of typography and colors. good job so far.
I have only one thing to add: Maybe try a font with serifs for the headers to fit the logo.
