So I want to clarify this for people, yes the art for Mewtwo EX is a bit odd, but PLANETA is an art studio with multiple artists, each card done by a different one specifically but they all pitch in one way or another. So PLANETA has always had a decent mix of awesome and lackluster artwork, and substantially more positive reviews than Yoshinob, but I digress.
While Mewtwo doesn't typically get shown to be physically orientated, the fact that this Mewtwo is the set up for the physical bruiser M-Mewtwo X makes sense. It is portraying what this Mewtwo wants to be in the future. Perspective wise, having Mewtwo's head be down with its mouth open is definitely a side of Mewtwo that we are not used to seeing, but nothing is proportionally wrong with it, its just awkward. It could be worse, it could have been Machamp EX broke sausage fingers.
