Yes I like Bumi, I like his character a lot, he is easily my favorite in Legend of Korra and I think he's fairly good looking, no I will not elaborate. I'm glad people do want to see my human art, it was a worry I had because I know human art doesn't always go over as well, but I wanted some variety to my stuff and this is something I wanted to draw.
Eating a lot when working for the United Forces was fine, he burns off all the calories doing his crazy antics. But now retired, maybe "eating to get his energy" is really just "stuffing his face too much"!
