Although this creature can look a bit fearsome , I based the way it's teeth are constructed by looking at skeletons of Diplodocus and other herbivorous dinosaurs, so it's pretty much harmless ;)
I really wanted to test the cool sub-surface and refraction features inside Marmoset Toolbag, so I made sure there are enough thin surfaces ( like the eggshell) that can react in a cool way with the lighting inside the scene
Also I've been seeing some amazing obsidian-looking materials posted here so i couldn't resist and made something similar for my scene .
all the textures are set to low due to upload limitations
