/cgl/ - Cosplay & EGL

Does anyone have like, a pattern for Junkrats arm?
I'm struggling so much I don't even know why
If someone would even draw in paint how their pieces looked that would help me tons

Not sure if I should ask here or in makeup general but whatever
What products could I use to achieve this look? Like, sooty, but kinda blended in to the skin?
Every cosplay I've seen of him seem to use way too dark colors and kinda only on the upper part of the face. I want it to look more like been there for so long that it's kinda part of the skin, like how it looks in game

I've done a few makeup tests with black eyeshadow, but it gets way too dark and not really blended..
I saw someone use like one of those makeup sprays tool thingys(?) but I felt like that also looked too dark

Any ideas at all would be appreciated desu
