This is a work in progress.
Here is an explanation on Wikipedia if any of you are unfamiliar with this term.
First I do lots of sketches- I use a classic 8 head formula- therefore all the horizontal gridding you see on the figures. I liked the pose below- but not the hair and flowers. The sketch on the bottom is not quite finished- I need to do more work on the feet and add a ruff- but I wanted you to see the grid lines before I erased them.
I used the Nitrams which I get at http://www.dickblick.com/products/nitram-academie-fusains-charcoal/
They make subtle skin-tones much easier and are not as smeary as even the best vine charcoal.
On another post, time permitting I will give you some clues as how I choose my colors.
