Wow, more amazing work here. I like how your "relaxed, easy painted" minis look so stunning
I see now what you mean by the small eyes on the 75mm figure. My take on this is always that the smaller the scale, the more the sculptor has to enlarge the features we tend to look for, eyes being a good example. At 28mm / 35mm, the eyes are super tiny so they have to be made over large. When you get to 75mm, you actually have a chance to make "normal" sized eyes but then they feel tiny in comparison to the smaller scales.
Regarding the skin, I am always amazed by how much light skin will reflect, especially in the specular highlights. The oilier the skin, the more prominent these are, and the drier the skin the less specular highlights. So maybe add some bright highlights? I reckon she will have perfect skin, not oily but certainly not dry.
