this is great , alot of pen tooling there ( I think), i want to see what it would look like in color too
do like an overlaying or lighten (layer mode) red color , so the black has a nice glow to it, if u don't mind I could try adding some color to it from this .png
looks time consuming, definitely original. for coloring id say go in a bit more depth with the guns for diff shades, green for money symbols, use ur imagination . blue's, reds, hell you could make it rainbow colorish if you wanted.
Wow nice, Good pentool work, wish i was that good with pentool. It obviously shows greed. Good luck with sotw
