I agree with Pappy who says "When I think of Eisenberg I think of his great composition from panel to panel and page to page, but also his action-filled artwork. His characters run low to the ground, and they always seem to be in some sort of motion."
By contrast, Kelly's poses, compositions and angles are less dynamic, but he brings other things.
Both Eisenberg and Kelly have the same background fundamentals. They were trained in the pear and spheres school of animation design.
I love both these artists, and it's fun to figure out where they vary from each other, starting with the same foundation.
