Im glad to see you are working toward more cleaned up animations, and i believe this is off to a good start.

I think you could work more with follow through and secondary motions of the characters hair to push the visuals more. I also think short action animations like these would benefit more in gif form in the art portal, i see a lot of thing like this generate more attention over there than in the movie portal since it is so short.

Keep up the good work though, your line art is looking nice and consistent, just keep in mind the other principles you could apply for more fleshed out movement!

The artyle you have is sharp and unique and feels grounded, however i have a few notes of our composition. In the shot everything is happening in the upper left corner and makes the rest of the image feel empty and unnecessary. I always aim to keep characters looking into the frame instead of outside the frame so that the viewer has a line of action to follow

I just gotta say, I love Mummy Ball. Like, i got nothing else, great shading and detail, especially the light reflecting on the bottom in the shadow!

I really like the composition you have going on with this! I would play up the style on Kingpins face a little more to help make him pop, maybe try some half tone dots or stylized shadows to better reflect how miles is simplified below!
