All of these models are pretty well made and have their own unique flair.
Alt Sonic's model especially brought me a pretty large amount of joy with how much personality some of his animations have. My only nitpicks (might as well be the most minor criticisms ever) are:
- The running animation is cool, but unfortunately doesn't transition too well into Super Dash Mode.
- Some of the frames for Super/Hyper appear to be broken, but I'm sure this is easily fixable.
Would recommend, the hard work shows. :)
