There's a good character design for this i'm glad you started doing a cleaner line work!
Looks really nice! The palette is clean and the lines are very clean as well! I'd almost say you don't need the colors you used for the whites of the eyes as it could be shared with the shine on the body, but that's very minor 
Great work and great improvements. Next thing, I'd say practice a little bit of colored outlines and AA here and there. Not necessary but something that's nice to learn and will help give your lines some more depth! Keep it up!
Nice sheen on the scales!
