My friend Zippiner went to FC and offered to get shark dog pictures for my sketchbook. I am fantastically pleased with the results.

This one was drawn by Aazhie! I love that it's based off of a prehistoric shark, and one of the weirder ones at that! The shark species is cool as hell and makes for a pretty awesome sharkdog concept.
