Looking nice, some critique though:
- his right arm looks really short and big, make a visible elbow imo and bend it a little outside
- his left arm is too long and has a weird bend in it, also the shoulder muscle is a little big
- left leg is good but his foot should be longer (and show a little of his heel)
- right leg should be longer and his foot shorter imo. also the yellow line of light that defines the bottom part of his leg could be a little shorter, or else the pose of the leg looks weird
but i love the face man awesome expression, very nice colours you picked too
looking forward to your progress!!
