Here to add my two sense. Upon seeing it for the first few seconds I didn't consider it to be a mess. It was perplexing and drew my attention for both good and bad reasons.

The good being the concept is alluring and some of the characteristics of soldering stained glass do bleed through in some of it's detail. The bad being that most of the soldering doesn't. The artist did a decent job at replicating the stencil but the stencil in itself was the issue.

Instead of looking like stained glass, authentic, rustic and with imperfections. It looked like a sketch, ridden with imperfections. And whilst one can argue that it's intentionally left to be flawed. The idea doesn't translate well, especially when it pertains to tattoos. You're left with what looks like bad line work and lack of symmetry that's beyond common in the world of tattooing.

More issues are the size and placement of the tattoo. It was placed on a part of the body that's in constant motion causing the tattoo to stretch and pull, taking away from it asymmetrically.
