Generally agree. but the line work here looks exactly like line work for tatoos on skin. If it was drawn on, you wouldn’t have the lines bleeding out and in to the colors of each other like the black lines are into the green fill. Additionally, the white wouldn’t be so white.

That’s the white color you get only for the first few months of a color tattoo.

Honestly, I think this is a legit tattoo.

Could be wrong, but it looks real.
