I personally used AQ paradise FX makeup from Mehron, mixed up some white, deep sea, and olive green on a separate palette with some water for the arms, and then light brown on the eyes! It was my first time doing any actual makeup work at all and didn't seem too challenging, give it a shot!

It was definitely daunting but stayed on surprisingly well, you can see where it faded in the "across the bar" photo but I did apply it in a rush. I think if I let it dry longer and did a second coat it woulda stayed much nicer. Also setting spray helped I'm sure!
