Sorry for the late reply, hope you still get this...
The shooting and editing is really strong here. You have some nice shots, and some nice sequences.
As for the music, I was once told that music is a crutch. I don't believe that to always be true, but what was the purpose here? Also, it starts off at a really fast and frenetic pace, which makes the dropoff seem even more dramatic once it ends. We go from excitement to it suddenly feeling kind of dull, when it might not have felt that way otherwise.
My biggest problem here is that that story *sucks*. I know that's probably not your fault, and probably not the reporter's either, but the fact still remains that the subject matter is an insurmountable pile of ****.
I mean, I know of no one who gets tattooed at home. Furthermore, the supposed "problem" isn't one you're going to find at a convention of professional tattoo artists. I get the impression that someone--a producer, a news director, or someone equally detached from the process of actually doing news stories--saw this FDA warning, and decided it coincided with a tattoo convention, and provided an excellent opportunity to scare people.
It makes me sad, because I'll bet you each and every one of those tattoo artists had some really fascinating story waiting to be told. Same goes for those who came to get tattooed. Or, a more general story about what it means to get a tattoo.
Anyway, I'm kind of rambling on here, but I want to come back around and compliment your work and your effort. It's clear you have a pretty good idea of what you're doing.
