From Kingdom Hearts! I've only played the first game back when it first came out. All my friends are in love with this game! This was actually a commissioned portrait and is the very first piece from Kingdom Hearts.
As per usual you have knocked Sora out of the park. I really like the colors and the way you shaded the metals.
Also if you have a ps3 Kingdom hearts hd remix will be out soon. It has 1,2, re:chain of memories as playable games, and 358/2 days which they have left as a 3 hour movie of the cutscenes. Not all 7 games, but it is a good start.
