Advice needed: location for a pin up

Per title, I’m getting a sort of pin up tattoo in a couple weeks and having a hard time deciding on location. I have a sort of sleeve on my thigh already and there’s some space on the more medial part, but I feel like I wouldn’t like this piece on that spot. I also work for a Christian retirement community; they don’t care about my current tattoos but I don’t think it would be a great idea to have a pin up on my arms for when I wear tank tops (I work in the fitness department). Any thoughts on location that would aesthetically make sense would be so appreciated!!!

I’ve attached the general idea for the design but my dope artist has redrawn it to look 100x better (the og is from a super old flash book)

Areas already taken up: right thigh has a patchwork sleeve with small filler in between, right back of forearm, both triceps and right biceps, right lower hip/upper buttcheek
