All and all looks quite good. Could be interesting to see if/what they'll make next. Counterpart would be interesting imo, partially to see if their anatomy matches.

But can do with a little tinkering here and there, though for a first animation, it's really good.

Not if you go with their body proportions. Then it likely can be too big even.
