My opinion.
I love him first off. I think his hands should have light webbing inbetween, not too much. I think his fingers should stay long and skinny, but decrease the webbing inbetween to make him have more of a horror look. I love skinny things. I think the skinnier the more creepy it looks. The rest of his body and head should stay the same it looks sweet. His feet should have more webbing then is fingers i think. Love this!
