I apologize for not listing WHY I didn't like it.
-The 3 dots on the bottom don't seem like they should be there.
-The colors aren't pleasing.
-Having a huge green oval in the middle of the screen is plain boring
-The screws look too 2 dimensional. Give them some depth; use shading
I also suggest you try not to go with an abstract design. The rectangular sites are always better to look at.
Don't dump this in the recycling bin though. If you still have the .psd, I suggest you change the colors, delete the 3 dots, shrink it down, and implement it into your website. It would be a nice home for anything real time... (clock, news, weather....) Make the screws "bolt" into the newer design.
If you spent as much time on this as you say, I would LOVE to see what you do with a few weeks of design... Nice work, and post back with the finished product!
