I wanted to make it olive branch-ish. Prison tattoos usually have a blue color because of the bad quality of an ink. It depends on what exactly you use as an ink so the color is changing from blue to green but yeah i could make it better obviously. My main goal was a smooth sketch as soon as I haven't been drawing anything except of a pixel art for last year or more. Glad to be remembered, thank you for your words. Much love
P.S
A lil bit more about these tattoos, I decided to draw them in the last moment because Vladimir's head looked empty.
