It looks cool at first glance, but I find that the SS looks like he is to the left of Thor and not about to crash into him. Also, if Thor was really winding up for a massive blow his left leg would be forward and right leg back so he could step into it. Finally, the SS is going to crash into him in a micro second. Thor has absolutely no chance of even starting his swing. Plus the SS is disproportionately small when compared with Thor. He looks like a midget to me.

You are absolutely correct.
I always thought the figures were angled oddly and presumed they were "cheated over a bit" to get a better "artistic" angle. I never picked up on the arm and leg dis-coordination, but you are right. It would be like a right handed pitcher leading with his right leg in the windup.
Not sure about the relative size. I always figured SS would be average size while Thor would be pretty big.
Despite its flaws, it is a great cover.
