This is lacking eyes and gill slits, and has human teeth with prominent canines. It's not totally complete, but pretty close.
This was made in Sculptris and actual shark teeth were too hard to make, so I opted for a funny set of human teeth.
It's my first digital sculpture, so it may not be perfect, but was a great learning experience and I encourage others to try Sculptris or other free software, because it's a lot of fun!
Looked at countless photos of great white sharks and played around with Sculptris.
