This is superb! The dominant wrestler is in total control here - I love her smug smile and the way she's reclining casually on her elbow almost gloating at her opponent. You get the feeling that she's really enjoying working the other girl over knowing that she only has to flex her legs to increase her suffering. I also love the look of distress on the other girl's face - she is desperate to break free but is clearly getting weaker as her opponent increases the punishment. I'd love to see more from this fight.
Have you never think to draw jungles girls? That could be interresting to see, with your style, women like Sheena or Rulah, fighting against beast like lions, crocodiles, pythons, or leopards. With the time your artworks become better and better.
