Mm, it's not bad, but I would've liked to see actual text/phrases rather than just random letters. I think the random green/blue spots of text could probably go too, along with the two random spots with typography outside of Gokudera himself.
I'm not very fond of the Gokudera Hayato font. It doesn't seem to really match the feel of the design (too fancy for it). But, the background and lighting looks really nice on it. Unfortunately, 1280 pixels wide isn't big enough for me to use...
