ok, i have a couple of things...
1. the background took pretty long to come up for me. i know it's a tough task, but i would work on decreasing the file sizes a bit on the images a bit.
2. i dislike the placement of the google ads in the center of the page. looks out place to me.
3. i don't like how the background just ends at the bottum and their is no real transition to the plain black background. but then again, i am at a higher res than most. however if i recall correctly, so are you. so just maybe you know what i mean. a simple fade might help smoothen it out a bit.
other than that i have no complaints. looks pretty good. you get better each time around.
