Thanks for updating the post with your concept art. I think the sculpt is coming along nicely! I like the pose and the details your forming. The coat feels a bit too chunky, both in thickness and general volume. For me it’s making the pose more difficult to read, especially compared to the version without the coat.
What’s making this difficult to grade is that there isn’t an explicit design of this character among your concepts. They’re more like utility sketches. Perhaps you’re designing the character as you sculpt. So in that way I can’t tell if it’s an authentic translation or more of an exploratory sculpt.
Either way, I like what you’re doing. Still unsure about the coat currently though. It’s a B in my book 👍
