Thinking about changing his blade to a blue wet blend to add some detail but not sure if it really needs it. Let me know what yall think in the comments :).
Hello! Face looks pretty good, I am not convinced about the number on his shoulder though, so if you feel comfy you can go and try to improve it. I also think the idea of a blue blade could benefit him, as it will be the balance between the gun and the blade, because now it looks a bit plain (the blade).
