19M How is my crown? I’ve always had naturally thin hair. Bad lighting?

I’ve recently started noticing there’s a spot on the top of my head. My dad isn’t bald but my maternal grandpa is.

Also I’d like to point out I’ve always had naturally thinner hair and I haven’t really noticed any significant hair loss. Is the lighting just bad or is my crown thinning?
