Worried about my crown

[hairy123]

Hi there I'm 19 and worried that I have diffuse thinning around the crown
In particular under direct light the top of my hair looks thinner and less dense. However could this be due to the way I wear my hair? (pushed forward)
I have some pictures of my crown under flash and then the top of my hair as well. Any opinions would be greatly appreciated to set my mind at ease

I'm not sure, looking at it more could it just be that I have a cowlick?
