Hmmm i think the two outermsot panels are the main weakness of this wall--they give like a faded, techno-tone look (if that makes sense) yet the two in the middle have more of a modern(?) twist. either way i think the color adjustments on the two outermost panels were unnecessary :3
but that being said, i love the design, its simple and sleek and we havent seen it in quite some time. i think you should have been slightly more careful with the text in the top right corner--the cyan is too bright and i think the font choice could have been better--serifed. the other text i think needs to have smaller line-height to get them more bunched together and look more like print than just random text
great job though, its been too long since someone has done this style =]

Very awesome ^_^
very simple but nice!

Wow O_o pretty amazing design, I like how this blocks looks! fav!
