18 and worried if im showing signs of early mpb

[jqf1]

Hello guys, Im 18 and im not sure if im starting to bald. I've been noticing thinning on my left temple which thins faster than my right temple(This could be a result of my extreme fade haircut that I get). Recently, i have also been noticing something weird in the crown area. Not sure if its due to the lighting of the pictures taken though. I was wondering if its the start of mpb, a mature hairline, or if im going crazy.
I've taken two versions of each picture in different lightings.
Any input would be helpful,
thank you

Men you're hair looks fine, but maybe your hairline is changing a bit. How's is it gong by now?
