There is a trick there, because a good artist will tell you if they're not up to the task, but a bad one won't necessarily. The best defense is to spend a lot of time learning how to recognize average work from great work.
Your tattoo isn't shitty - but it isn't world class, either. We've all had or have those, too. If you really want to commit to world class results you could laser at least the hair places a couple of times and lighten up everything. That would open up your world to infinite cover options with the right artist.
