For 13 though, it's not bad. Sure it's not "pro" like he said in the title but he's learning (aren't we all?)

Anyway my only adive to you would be to use your own creativity, make what YOU want. Don't follow every 'trend' thats the worst thing new designers can ever do. Also a few tips; small text IS bad, too many content boxes close up kills flow, abstract headers usually don't look too good and use colour. Grey really doesn't look very nice.

Good luck!
