Render is absolutely amazing, I love it. I would've liked it better, if you erased a bottom part of the render, to make it look like he was in the picture, and isn't just pasted on. Smudging, overall looks pretty good, and I like the colors, they go nicely. The left side could use a little work though, it seems blotchy and kind of ugly in some places, but the one overall problem is the light source. It's wayyy too overpowering, and takes away from the piece a lot. Lower the opacity on it, and It would probably look a lot better.
Overall, good job.
EDIT: By the way, I fucking loved the text.
