Dude, I think this is the best Reincarnation fanart I've ever seen! It's mostly because you manage to get into such a different style of the character while still having everything that makes him awesome! The best thing is probably the guy burning in his eye. The things on the right side look more like cats or animals than people. You truly get a look into this guy's madness. Or rather, his evil.
I don't even know if I've ever seen him this malovalent in canon. There just seem to be all sorts of things here. I think there are some rocks or what looks like part of a tree. You just made him a different character with these shadings. It's one of the best interpretations of another's work I've ever seen! Lilg is still great of course.
