It looks interesting but not sure how functional it would be. The float right, leaves a massive gap in the middle for people with larger screens, perhaps make that box fluid width?
The left sidebar seems a tad small to fit any content in. And I'm slightly undecided on the fixed footer at the bottom of the page. It looks good and makes sense but could become a tad annoying if your site involves a lot of scrolling.
Saying all that I really like it, honest! There's definitely something there, just needs a bit of tweaking
it's pretty plain really. I'm sure your thriving for a minimalist thing but to me this just looks blank. I think it could work if you were to give the background some texture thougth, maybe a big macro photo or something that's been desaturated & slightly opaque just so it doesn't take away from the text.
