I'm nowhere near an expert, but I'm gonna be brutally honest and say based on this pic alone you are headed for a severe Norwood 7. But thats only if the red arrow area is early stage hairloss.
If for some reason you shave that area, or keep it extra short because thats how you style your hair, then kindly disregard my opinion.
You also appear to have some retrograde hairloss happening, which doesnt bode well for the future (rear neck area, below your ears)
