Make the mole darker maybe and not so long in the face. Need some distinction between the cloud and his robe as it kinda looks like he's wearing Marilyn Monroes dress @ the moment. The rays of light are a nice touch. keep @ it.
Not seeing mole, maybe needs some ears/work on snout? His hands look backwards. The toga should be a different color than the cloud so it doesn't all fade together. The light rays are cool, maybe a halftone fade?
