the right side of the sig doesnt really blend in at all
i think you should have either chose the curly thingy or the mountain stock but i think mixing the two was a bad idea
the red glow on one of the arms seems a little strange and i dont think that many curls were necessary
the lines for the arms seems kinda wigly imo and the little lines coming out of the corners dont really flow with the sig because they match with the mountain but not the hands
props to you if you drew those arms
the black around the edges seems very dramatic and do help to create a focal
keep practicing
sorry if i come off as a meaney
