Variation on the Teardrop Tattoo?
I'm considering getting a single teardrop sorrow tattoo (an image of a woman's eye crying)

on my shoulder as a symbolic tattoo of personal grief & sorrow, however
I would think with your placement it would be fine but I'm concerned with the fact that you isn't really sure you want this tattoo because of what it could mean.
If I were you I'd talk to your artist and have them help you with this,maybe
