Show HN: I built an AR App that overlays makeup tutorials live on your face

I built UR Artist: AR Makeup Studio after seeing my girlfriend struggling to apply makeup outside with her tiny mirror and bad lighting. I thought to myself, that it would be really cool to have the mirror tell her exactly where and how to apply the makeup she wants. So the app was born ;). I would really love to get some feedback on how you guys see the app's functionality and where I could improve it
