Another one of these Pokemon drawing of yours that I love.
The really creepy thing, however, is that if you look at the Caterpie, the arms are in the poses of the people on "The Human Centipede"'s trailer art. In fact, someone made a "The Human Caterpie" parody of the trailer art, and it looks just like that Caterpie's arms.
Ah other said, this stuff would be GREAT in Don't Starve, the art style is so similar. Maybe check the game, see if you like it. There's a great support for modding, you could do some amazing content with your skills!
