Here's my feedback here: The trail animation pattern is fine, but they go up too high above the head. Maybe shorten the distance by about 10 pixels? The other thing I have a gripe with is that the green variant looks too similar to the blue team color. Maybe darken the green or cut it from the submission? The former of which would be ideal if you really want to keep the green version. That's all I really have to say on it, decent work!
