I'd say work on the front some more, the Welcome is larger than the logo, plus the logo really isn't working too well where it's at.
On the back I'd say a little less room between the headings and the paragraphs. Seems large and it's hard to associate them with the paragraph.
The top middle and lower right are a little empty and could use something there if you have any content, but if you don't maybe tone the background down some on the lower right section so it's more like the greens and reds?
i think this works well but the text could use some more styling. Try different weights and treatments for the headings. I like the different backgrounds on the panels, I would add some sort of light texture on the contact panel. Also, try adding a light drop shadow to the logo bar on the front to make it look like a piece of paper wrapped around the brochure. Lastly, on the logo, think about doing a reverse logo that matches the green a bit more. It's also quite pixilated.
Personally, I think you're off to a great start. The colour palette you've chosen is pretty solid (though I'm tempted to suggest an off white instead of the pure white, just to take the contrast down a notch but maybe you already have an appropriate paper stock in mind) and are very serene and inviting. The swashes are also a nice touch. The whole piece kind of reminds me of Autumn in the countryside.
I didn't really think so at first but after taking a second look, I think I agree with Eric about the logo. It works well within the banner but it's strange having "Welcome" so prominently at the very top with the logo sort of playing second fiddle beneath. And I'd also agree with Nate that the type needs to be spicened up a bit. Maybe a little imagery might help. There's just something about this brochure that just seems lacking... I mean, sure, it does the job and gets the information across clearly but I just think it could do with a little more spirit, you know what I mean?
I'd also consider putting the logo on the reverse above the contact information and on the cut-off comments slip as well.
The design overall lacks some unity. You are trying to squeeze a few too many things in only 4 pages. I would try something different for the "Thank You..." page that fits a little better with the rest of the brochure. Also I would suggest adding some subtle background to the plain white pages. Plain white can be very hard on the eyes sometimes. Changing to an off-white could work as well.
the layout is ok, but seems a little dull. maybe have an image move all the way across some of the pages
Very nice! The colors are very calming. The front panel feels like it needs something more - definitely a script font for the welcome text, and also for the panel that reads thank you for visiting. I think a silhouette image of a family at the bottom of that panel with the text at either the top or the bottom would work nicely.
