Practice makes perfect

Been doing alot of practicing lately to try to up my skills. A few things that I've been concerned about have been A) muscle sculpting, as I feel I did a dreadful job of it on Magnetos right thigh, B) Painting flesh tones, and C) Painting eyes. So I've gone to town lately trying to make sure I'm not holding back on certain projects because I'm afraid of trying one of those three things. Heres the practice so far:
