I believe I've mentioned before how you're getting closer to Genzo's quality for each passing day, and it still remains true. Although there's one thing for me to suggest, then there's: I wouldn't remove them. Highlights are a good thing, but only in the right places. In the case of Zor here, the moon is behind him and yet .... the highlights are on his front. Granted, the ground can reflect some of it back, but if the lighting is to work in that image, then you might as well remove the moonlight in the back altogether. Or to make Zor's front darker. So yeah, use highlights more sparingly. All I'm saying.
