I like it, it looks good.
The header image seems a little pixelated though, I’m sure you could get away with adding a few more kb’s.
Something about the red background doesn’t quite sit with me though. I’m not sure if it’s just too plain, or perhaps it’s that it stretches across the whole window, I’m not sure. Could just be me.
I’m not too crazy about the green on your header text. I think it needs to be a bit more punchy, drag the user’s eye to it. It seems to get lost in the background. I think just stepping up the brightness a couple notches might alleviate that.
