Overall design and theming seems alright, but I would suggest making everything a little more consistent. The current animations with the 4 boxes about halfway down the page are somewhat annoying, since every one of them has a different animation that takes a bit longer than it should. The first and last ones are the most aesthetically pleasing, so go with one of those.
Also noticed that the capitalization is different on your browser title and image, not sure if that's intentional or not
Only other thing that bugs me a little is the colour choice, and I know youre going for a coffee/grey look overall, but the white to brown gradient doesnt look very good on the title frames near the bottom, and I don't see why you reverse it between the first and second picture, so you know, consistency helps.
