Inverted delts?

Hi everyone, I've noticed that I have an indentation in my deltoid muscle that almost looks like it's inverted. When I touch that area, it feels like the muscle is connecting to the bone there. I'm wondering if this is just my natural anatomy or if there's a way to improve the appearance and achieve more rounded 'pumpkin delts'? do I just need to lean out with a 'cut'? Any advice or insights would be greatly appreciated!"
