Ideas on tattoo placement?

So I know I want a tattoo of a whale, preferably no bigger than a few inches across, but I'm not sure where to put it. My favorite placement is the inner arm right above the crook of the elbow, but I'm graduating university soon and will probably be interviewing, so I'd prefer somewhere than can be easily covered if I get a job that doesn't like visible tattoos.

I was considering the area below the armpit and back, like at the bottom of the shoulder blade if that makes sense? I'm female and I don't plan on having children but if I do get pregnant, I'm not sure how much that area would stretch with growth since it's near the boob. Also I don't think I've seen a tattoo in that specific area so maybe there's a reason for that that I haven't heard.

Any other ideas would be greatly appreciated!
