I love it. Couple crits:
- On the back view, because the visible hair resembles ears, I'm seeing a really big Link head on a Goron body. I don't have any suggestions for how you'd do it, but I personally would like to see something a little more to make it look more natural. The body and feet especially look very good though.
- Similar thing on the side view, in a sense. It seems like his hat covers too much of his head in the side view; specifically, it dips too far down. I don't even think a hat would stay on if you wore it like that.
Positives:
- I really like how the animations match up very cleanly with Link's. It makes sense that Goron Link would run the same way as normal Link, since he's just the same person with a different body.
- Deku Link looks great. You really captured it, I think. I would like to see some red in the eyes, though; having them just yellow throws me a bit, since his hair is the same colour.
