Punished "Venom" Snake

Starting with a new likenes study, yeah it's a ficcional character but i want to improve it to make a photorealistic render, but first i want to master his sculpt, and i need some tips about the skin and the expression too. You know, i didn't found his soul yet.
PS: The Hair and the beard is just a proxy reference to sculpt, i'll work it properly later.
