Well they're pretty good, but on the grappler's head you didn't outline the face completely like you did with the warrior. Also I don't see the warrior's eyebrows being thick, also in her battler she has upward tilted narrow eyes, not normal big male eyes like you gave her.
What I'm saying is you outlined the warrior better but you made her look masculine and innacurate.
Edit:
Oh yes, also wouldn't this belong in the resources topic?
