As a fellow fan of predators, this sculpt is looking badass.
got all the details in nicely, especially great work on the head, the cheek flesh looks and feels really taut and stretched.
if there are any crits, i reckon spend a little more time on the feet, wrists and proportions. the feet are a little bit too incomplete/short and dont look like they could realisticly balance the character when posed.
the lower half of the arm is a little bit too skinny compared to the rest of the characters beef, and the proportions of the legs to the torso seem a bit short. it may just be all the muscle, but i reckon either the torso needs shrinking, or the legs needs elongating.
good luck broo, keep up the great work
