I'm still in awe of your color choices and the way you render things in a sketchy/painterly manner! It really makes your subjects feel alive. :D I would like to mention that this character's skull seems a bit too flat, even for a reptile creature. Using a warp tool and "pulling" the head upwards a bit from the top could round it out a little more, make it seem fuller.
Still, great work as usual! Always happy to see your art. ^^
