Frill Shark Failure :(

That’s my design for our 3D project at the Uni based on a Frill Shark. But, during the briefing I was told to make something simpler (as were most of the others) I kind of understand that (never touched 3D before in my life), I still like it, so perhaps when I learn more I will come back to it
Now I have to make a different design. I already have some ideas, hopefully they will get through
