Is this a normal hairline?

[venture22]

Im 19 years old and lately have ben noticing a more defined hairline. My question is if this is normal looking, or could it be the start of a receeding hairline? My hiar is very thick all over and i have always had a big forehead

Looks fine to me.

It also looks fine to me as well. But... in my opinion, I cannot tell for sure because I haven't seen any possible "before" pictures to compare if your hairline receded or not.
