"Sloth Pounder"
Missing seeds aside, the bun is a little too perfect - though not at all bad. (More of a television advertisement bun, rather than something I would actually receive at the drive-thru window.)
The sloth, itself, though, is very nicely rendered!
Note: Besides the thin borders breaking with tradition, they are also so thin that they almost act like, or want to be, comic outlines. Case in point, the title above. One almost expects the thin border to completely surround the burger, and it looks kind of odd on the far right hand side where the bun continues, but the border doesn't.
