Chris Evans as Cap. I think this one was gouache. Which I always mispronounce as gauche.
Grace Kelly, Transparent watercolour.
I screwed up Grace's ear when painting, so I fixed it in Clip Studio Paint, which I find paints more naturalistically than Photoshop. I think I just was so happy with how the face turned out (after a couple abortive attempts) that I wasn't paying attention to what I was doing.
