i drew the guy first, and because whenever i move him the pixels get lower quality, i just moved him around a bunch of times until he was basically blurry
for some reason whenever i use the fill tool aswell after, he gets more and more opaque so i just filled in a few things and watched how much of an eldritch horror he could turn into :'D
i dont actually know how i got the smudgesm but i rememeber using white on those areas instead of eraser
