Was pretty fun, maybe took ~15 mins or so, so might be rushed in a few areas. Pretty happy with the result though.

Looks awesome. BUT maybe make the background a little red to match the render? D:

This looks cool, but definitely not your best work. I think it needs to be blended more and the colours don't match up great. Good effort though, and i like it!

Looks quite good, but it's hard to see where the render stops and the background starts in the area underneath his right arm (our left), which isn't a really good thing in this signature.

It's really good ( :thumbup:) but I have to agree with Jopie, the background should go with the render a bit better.
