Hades WIP Picture

This is my first real attempt at coloring in photoshop. finally putting my tablet to use! well anyway, this is my take on Hades, one of the three brothers in Greek mythology. gonna try and do all three in photoshop. busy drawing poseidon, hos a kinda buff armored manly man. not sure what to do with Zeus, I think I might draw him as a small teenage boy, seeing as he is the youngest of the brothers, and I think it fits his attitude aswell. anyway, gonna color this one completely and do a nice background, add some gems that sort of thing. any tips people can give me with photoshop coloring would be great. been reading a bunch of tutorials, but just anything you've personally found thats useful would be appreciated
