DD #21: Sunday Special

By having no chance to get in touch with my Bamboo today I decided to run a new round of "Sunday Special". Our special guest today is multiple: first I found the great da-vinci-like thread by Michael Mentler on conceptart.org and studied his hand bones studies (1, 2) (very useful: the 3-to-3 grid!), then I started to train figure blocking on posemaniacs and last I tried some basic real still life studies. At least 4 hours pencil work - I felt pale gleams of perfection running through my veines.
Am I obsessed?
