Ahh man I love this art. Looks like a bunch of mangled body parts fused together. You really showed how Jin-Gitaxius' experiments are made here, even without showing any of the process. Very impressive.
I thought that mask was teeth on the card- so much creepier when it's large. I absolutely love the color scheme, and the composition (you miss it at normal size). Though I think some of the main character should be less rounded, esp. in the arms. ONly crit I've got ^.^
