Liking the V one, and the Corpse Bride one is done pretty nicely as well.
Work on some colouring because some of the colour schemes look a little off.
Your newest one at the top looks really great, V2 being the best because of those few touch-ups. I would just add some text and see how it looks, maybe set out a defined light source, and try a gradient map set on one of the blending modes and then lowered in opacity so that you can get some nice colour and shadows out of it. :D
Can't wait to see some more!
