I am a member of a group on the DeviantArt! website that has a SharkWeek challenge every year. The moderator posts the name of a shark every day. Every day, everyone in the group draws and shares their version of that shark. I look forward to this; it makes me draw something every day.
Today's shark was the Gully Shark, aka the Sharptooth Hound shark.
One of the challenges of this exercise is finding good source material. Although I draw in a "cartoony/comic strip" style, I still try to get the basics of my sharks correct. This one was a tough one. I was unfamiliar with this species (found SE Africa, from Angola to S. Africa). My books were no help, and there were very few pictures on Google Images that weren't fishing photos.
Anyway, I think he came out pretty well.
