I am struggling with integrating the character with the background (something I ALWAYS struggle with).
One of the GLARING things I see right now is that the background doesn't seem... well, lit at all. that's giving me the impression the figure is pasted in... there's no real light source to match the figure and background. He's not casting any shadows so he's not grounded, either.
"She took the ice cube trays out of the freezer. What kind of a sick bitch takes the ice cube trays out of the freezer?"
I had just roughly sketched it in.. so that may be a lot of the issue. At lunch I am going to try and work on the background a bit more. But yes.. I agree. He pops out a bit too much. Putting in backgrounds is a weakness I'd like to overcome.
I think you have roughed out the background pretty well and the perspective looks good.
His upper right arm wouldn't allow for his forearm to be rotated that way. The bicep is turned towards his body and his hand is pointing away. The overall pose off the arm is fine just need to move some anatomy around. The left arm looks like it is broken mid forearm.
