Okay, I REALLY enjoy the hues you have opted to use in this particular coloring work here. ^^
Opting for a more blueish-green tint as you did here, rather than a brighter green as is normally seen in the Hulk's more common color scheme, creates a really sweet flow of the shades of colors from green to blue as one views this great piece from top to bottom; a real treat for the eyes indeed!
Again, exceptional coloring work here, pal; I'm very impressed with your awesome work! ^^
