As one artist to another I feel honour bound to point out a few issues; the arms are proportionally too short, unless the elbows and shoulders are back, causing the upper arms to be foreshortened, however it looks like the arms are straight because of of the modelling of his jacket. I also find his thighs a little narrow. His open eye looks totally crazed.
The weapons rock and the overall inking quality is superb. Nice work.
