I like the low poly esq style of the animation as it makes it very stylized, however you may want to work on things such as "floating on the ground walks" and "robotic gestures" which does seem to make the animation a bit stiff, unless of course that was deliberate with the style but I wouldn't know, its a minor nitpick but other than that good job!
Thanks for the response! This was from over a year ago, and I have gotten so much better at humanoid motions and emotion and whatnot. The problem with this one was that I had a week to do it for my sister's school project, and I couldn't find the file afterward. I appreciate and welcome the criticism, so thanks.
