Thank you for constructive criticism. I added a video link to the description to help visualize what I was trying to achieve in this two frame animation.

These two frames feel very disconnected, and I think that's for a few reasons:

The motion smear on the hand in the second frame isn't following from the hand's location on the first frame. It's not enough to have a smear coming off of it; the smear needs to carry the watcher's eye from the form in frame one to the form in frame two.

His feet are both in completely different places in both frames. In real motion, one of his feet would serve as a pivot point and should be in the same place.

The second pose also disagrees with your line of action. You're moving from the right towards the left. You don't go from the position on the right (wide stance, towards the left, ready for a lunge) to the positon on the left (narrow stance, facing camera,  over-the-shoulder backhand) in the space between two frames.

The frame to the left is unreadable. 

This is incredibly difficult to read, and the speed of the animation definitely doesn't help. I've been staring at it for quite a while, and I genuinely can't tell what's supposed to be happening, even with the context of the title.
