Glad you find my comments encouraging! I only said what I said, because its true 😀
I'm quite in awe of this drawing. Hands are pretty much the hardest thing to draw and its really difficult to get them to look right. Don't think I could do it like that from scratch! Did you have a model or a reference?
I like the use of colors. Many of the old masters used green for underpainting skin tones.
I usually pull up more than one reference. Once I get the structure down then I’ll sometimes tweak it.
I’ve seen that before. There are a few other artist that I’ve seen start off with cool tones and then build with warmer tones. I’m pretty happy with the colors. I thought about adding yellow but that would’ve set me back.
