Does my balding pattern look established?

I am a 31 y/o with substantial hair loss in my frontal third and crown areas. I've attached an image showing my hair at various lengths so you can see the full picture.

I'm sure I can expect to see additional thinning in the areas that have already thinned, but given that I still have full density in the surrounding areas, I am wondering if the hair loss area is pretty much established, and unlikely to expand to a larger area.

I am considering a hair transplant to fix the frontal third and maybe add a bit of density to the crown. However, I want to know if there is still a strong possibility of the crown loss region to expand or if I am likely to just eventually develop a bald spot of the same size as the currently-thinning region. Thanks so much!
