Gustav the bear - Idea!

This is the concept for Gustav in the new episode (5). I know it's strange!
Maybe it should be more like the prince, but I thought this design would be correct. What do you think?

Since I am very bad at drawing bears, I was looking at artists' drawings for reference, and there was so many cute bears hehe, I hope to know his opinion, should I add something?

I think making him big, muscular and fat, and it could be something so different from Gustav that I like that! Now he dont know really if this body fits well with him hehe. 

Thx for see guys ;)
