Bolty!

First time posting anything. I think it portrays Bolt’s intent, indomitable nature pretty well, if I may say so myself!
PS: I don’t like how his fur covers his collar, so I included two versions, one with his iconic collar, and one “naked”.

It's actually based on a generic dog template. I made some changes to make it look more like Bolt, and when that didn't work, I drew it all myself so that it would be Bolt although I still based it on the template. I found it somewhere on dA or Fanpop but can't remember the artists!
