wip painting

[par gin]

Here is a wip image i'm working on. I want to work it up to a fairly polished painting. Still in pretty early stages, so I'd like to get some feedback along the way. This started as an experiment in Alchemy, and I decided to turn it into kind of a creature/character portrait with a cinematic feel. I want him to be entering some sort of cavern dwelling where he's not sure what he'll find.

So how about the composition? I tried to set the character in the middle third and his lantern in the right third. I'm also no sure about lighting, if the light from the lantern is hitting in the right spots. Any other problems you guys see, let me know.

Thanks in advance!
