Hulk Vs. X Men

So here is the final result, I like this "from gray to color" technic, it makes things faster, this one took me 3 hours non consecutive, it would have usually taken me I think 4 or 5 hours, I know that's slow, but with practice I might get faster, I have already improved, anyway I still have to work some more on getting the tones and variations I want in the pic, although I think it came out good.
