How to draw Mewtwo

This is how I started drawing Mewtwo, the guidelines are pretty basic on this concept, also adding variations the human anatomy like elongating some joints, which are emphasized on the leg part and also the arms but not much difference. the tail is basically a ball outside of the body connected by a line which serves as a reference line in drawing the tail, start on the ball going to his body, gradually increasing its width as the tail moves closer. I hope that helped for all those who want to draw an awesome cat!
