Hello everyone!
I am working on a likeness of Samuel L Jackson as Mace Windu. My plan is to post progress here and hopefully get some feedback from all you skilled artists.
So far I am still working on subdivision levels 1-3 following the workflow Adam O’Donnell shows in his Obi-Wan Kenobi course:




And here are the reference images i am using:

When adjusting planes pay special attention to the cyan triangle/square at the root of the nasolabial fold. This inconsequential little plane is what sells the idea that there's a skull under all the skin and mass in the center of the face. Also, depending on the age you'll want to give the apple of his cheeks and upper eyelids more tonus than the painting above.
That's it. I hope it helps, and I'm looking forward to see more!
I really really appreciate the feedback, very kind of you to go through the trouble of making a paint over. Apparently he was around 50 when they filmed Star Wars but I don´t think he looks a day over 40! Gonna be posting more as soon as I get some of those changes in
