Where are his hands?
He was fighting with T-rex and he lost his hands .
Seriously, in the reference I used the hands were barely visible, so I decided to leave it with just one little finger.
Did you use just a single material setup for the whole model?
If you would like it to really stand out, then it needs separate shading for the inner mouth, teeth, and claws. I understand that fleshing such a model out fully can be a daunting task if you’re new to Blender, but the knowledge gained should be worth it.
No, I used just one single material for the whole body. Thank you for your advice, I will definetelly try it out in my human head model, that I’m working on.
