Nice! There's a lot of things you can do when photographing it to make it work better though, for instance, putting it against a wall can help make it feel like it has to be popping out of the paper. Also, when I'm photographing it, I make sure to take a lot of shots from a lot of different angles, because finding the absolute perfect angle is really difficult. One last touch that helps is drawing some shading below him, because if he's popping out he needs to cast a shadow. Doesn't have to be complicated shading either, but I think it's pretty important for the illusion.
