Alien Painting: Duros

I've decided to paint some more aliens and thought I'd start with this one from Star Wars.
It's called a Duros.
Drew this line drawing at work in a meeting.  

Then took it home and began painting it at night.  

I've begun to blend in my pen and pencil lines. 

Added some more detail around the eyes and on some of the skin.  

It's hard for me to stop working on a project, but I think I'll stop here for now. may come back to it later on.
