Drawing a snow leopard

Started drawing a snow leopard. I work on charcoal stuff in brief moments between doing everything else, so here are my first two moments spent on this drawing. If I weren’t legally blind I could get this done faster.
(First two sittings on drawing.)
I start with the absolute darkest area of any charcoal drawing and work out from there based on the degree of lighter shades, and in this case, the starting point was the dark spot near the center of the eye of the eye. From there, I can adjust for the right shading everywhere else.
