Desperate help neeed with tattoo idea

[Bexa85]

Morning. I have a few tattoos on my thigh/hip area and they just don’t gel well, they’re all the same theme but I want some way of blending them, adding something in the gap that I have. Any advice greatly received
i have included a pic. The top one would be inline with underwear but pulled up to show the gap etc.

You could have some geometric dotwork to fill in the gap?

If you're brave do it all the way the inside of that buttcheek and will look amazing
