actually i love it and dont think it is poor work at all, the only thing that i dont think is 100% is the music notes etc around it, but as for the guitar its very detailed, takes a lot of concentration to get a long line straight freehand.
A nice tattoo, but what are stars doing in with musical symbols? And shouldn't those dots be next to the quavers? Perhaps it's just me being picky. As I say though, nice tat.
