I'll give some CnC. I like how you did the colours for the bg to match the render, and I see some blending being done :3. Although what I don't like is that it seems flat. You need some more depth >.<.. You also probably should've blurred the torso of him so our focal point is his head rather than the whole render itself. Also, if I were you I would've added some more lighting, it seems to me that the light source is the top leftish? (guessing after looking at it for like 10 seconds) so you should've made the top left corner brighter and the bottom right darker o_o. The text is bad as you know, text is a bitch :3. The size as said earlier is too big for my liking, although that's just a personal preference. Hope this helps? Maybe? Or I'm just being mean, I don't know. Long day x.x
