So I have this issue with my illustrations in that I'm quite obcessive for details. I will draw all of these details on something regardless of if you actually see then in the final piece.
So here's what I finished today, I figured I'd post it before it gets covered with arms in the final picture.
Also, this website has the most amazing reference for firearms I've ever seen. Mainly because you can search by the film you may have seen it in. Handy for my current illustration, and is the reason why I know what gun it is I've illustrated.
