Have numbered to help on this one page.
The colours need to be simplified - less of them - I find it a bit of a visual assault right now and can't make head or tail of what I'm looking at.
I do like the silhouette against the stripes but why the empty stripes and blank colour stripes? I can make no sense of what colours relate to what? Why is Web and Product Design blue? Why is Logo type blue on green? I would like the colours to help me to navigate and find links/hierarchies.

Plus the Dilli part isn't reading well. The whole thing feels like it needs more impact
Welcome needs to be given more emphasis. This feels more like a word document put online right now.
Also line height feels tight
This is similar size to the Welcome bit at the top and a different colour again.
This is your main selling point - your work but it's tiny. Maybe think of another way of incorporating this or making it larger and the blurb smaller with shorter line length which will help its readabilty.
This would work much better as a jQuery slider - maybe make it into a navigation area
I linked through to a lot of the inner pages and the print area would be nice to have some visual links to your work.
Not sure why you have a plane here?
Hi Nitin
Sorry to say but this isn't working for me... The colors are ok, but a little over the top.
IMHO I wouldn't add a tagline such as yours creativity at it's best as the website, is very static.
I have added my notes, so you can see what I mean...
The contact page should have a contact form, especially as it is a commercial site.
Good luck I am sure you will do a better job on the second round.

would be a lot cooler if it was a jQuery slider and it enabled the user to see a showcase of some of your work.
I like the idea of selling your selves, that's great but don't justify the text, or if you stick with the justification make the content area half the size. Also the color of the text is too bright on the white background, and I am not 100% sure you want to say that the company is Off Beat, that would put a lot of clients off.
maybe change this to "portfolio" as catalog makes me think of a product, which you don't offer
Generally these days the trend is have more info in the footer, whether it be a contact form, social icons, or a duplication of the navigation, adn don't forget your copyright.
Always a good idea to have a home button, users generally aren't as smart as designers think. So therefore you want to make the site as simple as possible to get around.
Thanks Aaran, very good comments, i will work in refining it further and yes i totally agree with you. Thanks
Have you looked at using a grid system to lay this out.
The 960 grid system is a good one. It may help you align things.
Also look at hierarchies and good principles of web design. There are good articles on Smashing Magazine.
Also maybe look at using less colours - use something like kuler to get a base to work on.
Logo needs work.
Typography - agree with Emma that it looks like a word document put onto the web.
thanks Kate...surely will look at the grid system layout thanks
Vertical bar are dificult to read, sometime it's blue on green or blue on blue etc... there is no concistancy
The buildings of low mean what? I do not recognize them.
Otherwise, it's a good start
amazing feedback thank a ton..will have to look at all the feedback and then refine this further :)
