Mischa:
Thanks also for your feedback! I have not seen Greene's DVD, but I will look for it.
This latest drawing was done using the CarbOthello sanguine pencils that Maugnan recommends in his book. I found the color to be too intense for my taste and will likely go back to my Cretacolor sticks which are not as intense and I felt more workable. I will look for the fusion charcoal sticks you recommend and give them a try as well.
I also have some sticks in umber that I want to give another go.
