It's okay, but not really something that I would favorite. It seems to have an odd relation to the art used in : The Game : which was a really nice art design.
Colors - The colors were alright, seemed to be okay when related with the character, and the background he was standing in front of, they could have been a little darker, however. The bright colors don't really compliment the character.
Character - The Hulk was always more of a bulky character, and it just doesn't seem right to use him in a light where his is muscular around the top, but very thin near his waist. You should have added more bulk to his waist area, so it would look less confusing, and more stylized and normal.
Overall - It is an okay picture, again, it isn't perfect, and your style could definitely use some refining before you considering making further art. It may just be me, but I'm not a fan of this particular style of art being used in anything serious.
