It definitely needs something to get rid of that paint look, maybe from lighting effects and some layering to give it that extra umph, plus with that look maybe give it a small border
There is a small black border, perhaps a white border might have been a bit more effective? The reason he's a bit blurry, was cuz I used a few blur techniques to layer beneath stardust, oh and and the lines in the middle are a slight grunge texture overlayed on stardust!
