I have a little suggestion: next time you color light skin like that (and I'm just learning to do this too, haha) try using more browns, pinks, and blues rather than grayed versions of the midtone. It'll make your flesh a lot more lively :)
Excellent job, overall :)
That is a cool creature O_o..great job and good luck on your next art thingys :p...Kweh¿?¿?
