I like what you did with the pic, but the white line at the bottom just disracts me..if you edit that out it'll look much better in my opinion. It's better than some of my first ones so you're on the right track.
Its great! Being simple is best because alot of people prefer much simpler objects, (such as your avvi.) It is really good but, as Droid4Productions said, if you efit it, to take away the white strip at the bottom, it'll look 10x better! <3
