Ohmy what a cute animation you have here. I like when art gets some animation to it, it shows what artists are capable of if they took the piece even farther, and I think you have some talent here. You should keep this going in an animated feature on the portal. I love the expression in the faces that change with each jump, and the change of body movements. You've got some 3D effects going on in here, while mixing it up with 2D and I love it. The background is cool too with colors and shapes. Goob job, hope to see more soon.
~~THINGS TO IMPROVE ON~~
I would just love if you made this longer into an animated feature.
