For what it's worth, I sympathize with your feelings. My second tattoo, I was 18 or 19, I went to a highly recommended artist and explained what I wanted: a very simple Enterprise (from Star Trek...total nerd here). It was on my foot and I knew that foot tattoos can be problematic so I *wanted* it to be simple, almost cartoonish. Anyway, the guy was also a Trekkie and got so excited about doing it for me that he drew up a super complicated, very realistic version. And young, dumb, naive me didn't want to hurt his feelings (*eye roll*) so I let him do it. It looks great. Seven years later it still looks absolutely perfect...but it wasn't what I wanted.
But. I have grown to love it. It wasn't my vision, but it was a learning experience and taught me to speak up. It has made all my other experiences with an artist better and therefore made all future tattoos better! So I don't regret it. And honestly, it does look pretty cool.
A lot of people have stories of a similar vein - tattoos that they initially regretted but grew to love. If I were you, I'd focus on your next piece and if in a few years you still feel the same way, then go back and see about a cover up!
And! I actually really love your OG tattoo design!
