College Project - Online Feedback Form

Me and a friend from college are building a website for our 1st year HND Project, the website provides a service similar to uploadit.org...
At the moment we're experimenting with a few website designs and as part of our research need some people to view our designs and rate them (using our feedback form.) The designs are very simple but this isn't a concern. Our concern is ease of use/how well the site is displayed in various browsers etc
The website is www.swdl.org and the feedback form is situated here
Any help would be much appreciated :)

Site one was cool, I think you could continue working a bit with that one, or you could use the third one..which was nice also..a little bit more happy colored! :D Good work, and btw welcome to Hexus!

Quite liked the simplicity of Site Two... tho Site Four will prob be the fav.

yeah very nice :P pld

Liked site four but I dont like the way the navigation links bump the rest of them down when you mouseover them.

Site two, simple, fresh, colourful.

Thanks for the feedback guys it's much appreciated...

three was my favourite really... Keep up working on it all mchammer :)
