I have for a long time did not draw pictures with a full study of light and shadow. And I wanted to know what I am capable of in this regard, to be honest, I expected the worst)
And I liked this degree of elaboration of the drawing, although it takes much more time and moral effort^^

And by the way, the picture shows a girl from my closed species. I really liked her design, although I had to suffer with drawing a picture on her legs)
Sooner or later I'll finish her concept and offered for sale.
