Pretty good job on him! Funnily enough, you kind of got some traits of him mixed with his rival and protagonist of my comic, Alpha Alpaca. He is mostly stoic and serious, but he is a gentle soul and can be incredibly ferocious when he needs to be. Hadn't thought about about the losing his loved ones or people mocking him for his fur, though. (Most people mock him for his hurricane and ice breath.) Might want to keep that in mind for him in alter stories, though. (He actually leads a Super Sentai esque group of heroes known as the Four Winds and he's dating one of them.)
You did a pretty good job on him, all in all. Might submit another character later if you're fine with that. (Was gonna submit a DRGN character, but I'm currently in the middle of redesigning and updating them.)
Here's the topic I made that didn't go anywhere unfortunately. (Right when I got to @Chita's characters as well, funnily enough.)
