I use to draw a lot of Sharks when i was young, I think it's even one of the things that made me working in the art field.
I saw the work of @Olivier Désirée (https://www.artstation.com/capi974) on Instagram and immediately enjoyed watching his sharks sketches. Of course I planned to make
some in 3D, i choose two of those, from a really rough sketch full of life.
