Shark-dude

I have no idea what to call this. I just randomly came up with the idea and had to draw it to see what it would look like. I based it off of a Great White Shark, since that's my favorite kind I drew a mermaid to match, I'll submit that soon. Anyways, I'm really happy with how this turned out, especially since I didn't use a reference for the pose or face.

What do you think? Any suggestions on what I could call him instead of shark-dude? (mershark? sharkman?)
