I only see one drawing. It looks like The Punisher and Guile got mashed together. Kinda small to give a decent critique on. off the top though he has no wrist, and some of the forearm anatomy is wonky. Not much of chin on this cat either. The shadow on his left trap seems outta place and makes an odd area that attracts the eye.
Keep posting man. The more we see your work the better to guage and crit.
