Love this mod, you did great and as a moveset it's a great adaptation of SSB Pika!
I have a couple of things on the cosmetic side, though, if you don't mind the feedback!
First off I noticed the model has a flat shade, aka the polygons brighten and darken on their own instead of being consistent all around the body. Changing that to Shade Smooth (if you used blender ofc) could fix that!
Second, a bit of a shame this is not recolorable. Maybe you can make the textures decals (like Mario's eyes or mustache) and make the rest of the body recolorable without affecting the rest that way? It could be worth a shot.
Either way, this is more than functional without those nitpicks, you did an amazing job, keep it up man!
