It's been done a million times before, buuuut I didn't much like Kodi's design so here's how I'd change it! No huge changes really, he's built a bit more like his daddy (although slightly more solid) plus I tweaked his leg and ear markings to be more like Balto's. Fur is a slightly more natural colour, not as burgundy as it was in the film - although noticeably darker/browner than Jenna's, to distinguish him from her - and the lines on his muzzle are gone. Personality-wise he's the same ol' hardworking happy-go-lucky dude we all know and love.
