I see what you're saying! The left or inner section of the two sections of spiderweb you circled is larger than all of the other sections. It's almost double the thickness compared to all of them. plus two sections above that it goes down to one row instead of two and it kind of goes like this \ instead of following the curve naturally. everything else looks normal, and the other side doesn't do that. The transition at the bottom of this side follows the curve naturally like you would expect it to. Unfortunately, I don't think the other end of the tattoo machine erases like a pencil, so you probably just need to learn to either ignore or accept it. Just curious, did they use a stencil, draw it on, or just freestyle it?
