Finally updated him a bit from his old concept, which was submitted to an art contest of a character redesign and didn't make the cut.

It's so different from the original rainbow thing that I can safely keep this, now that I've gotten rid of the markings that were reminiscent of the other character.

I'm actually quite happy with those hand sketches... I guess if it isn't quite human and I'm not thinking about it too much, it'll turn out. XD

As a side note, for size reference, the top of a 6ft tall person's head would reach about midway to his forearm.

It's kind of a dragon/sauropod mishmash, I guess? The inspiration actually came from this: sta.sh/0vq4k8ketxo
Just some paint spatter on the asphalt near my car I saw the other day.
