These are lighting roughs I did as a quick demo for my painting class. Gouache and prismacolor.

Here's a demo sketch I did for my head drawing class, I thought I'd pass along a few pointers to those of you interested.
First, simple but accurate construction drawing then massing the light and shadow, this should be as simple as asking yourself what's in direct light and whats in shadow. Then addressing the turning forms within the light and shadow and designing hard and soft edges.
This overlay shows how a simple construction drawing lays the foundation. Though it may seem a bit abstract, it helps place the larger masses of anatomy within the whole, it maintains the symmetry of the head and helps convey the simple three dimensional nature of the head (like longitude and latitude on a sphere).







I've darkened the line drawing significantly here so you can see it, the original is very light. There's a little bit of red prismacolor lay in then a Ritmo B charcoal pencil.
Lay in with a compressed charcoal stick.
Half tones blended in. This is all done with my fingers guys, it's not a pretty process but it's the way I like it.
