That girl on the left has some cool-ass cyberpunky hair.
That’s most likely the result of a lot of dust/dirt and wind I think.
Do you think? I couldn’t figure out why she had dreadlocks.
My hair gets that way after a night’s sleep or when taking it down sometimes. That expression on her face makes it seem like she just doesn’t care any more and let it go.
