Oh wow, I guess I'm weird then, because I sort of prefer the green / black shiny sprite. The red / black looks a bit cooler I guess, but it looks a bit unnatural. However, that's how shinies work I suppose. But I still support the green / black one.
Also, Scorpio, the fold in the body at the right seems a bit strange, and I think you should push the back length of the body a little bit higher / lower. The current position looks a tad bit awkward. Also, the neck seems a bit thin. Good luck! :)
