I remember reading about irezumi tattoos (which are synonymous with yakuza thugs) and when they said that a true badass takes the old method of bamboo needles driving the ink into the skin over using modern tattoo needles as the latter shows weakness, I realized such thugs are ones to avoid, at all costs.
Then again, my threshold for pain is obviously on the weak side.
Great drawing! Never thought of doing a fanart as such. (Twisting the classics is a favorite thing for me.)
