I think it looks incredible. Personally, a little simpler but perfectly executed is ideal. Maybe the skin doesn’t have loads of stuff going on but not everything needs to be busy all the time, the boils and wounds it has look great. My personal opinion would be to just vary the color of the boils to include some purples and blacks like bubonic plague or maybe some bright infected greens or oranges. Maybe even some gooey leakage from some of them?
Too much “stuff” gets cluttered to me sometimes, I think color alone could give a little more variation. But you guys are WORLDS ahead of me in terms of skill and knowledge so just my $.02 to be taken with a grain of salt. Awesome work, truly amazing skill with a brush.
