Oil painting lesson with Gregory Smith

I started a new subject today. 

Because I enjoyed the previous project, which involved very few colours and tricky subtle tonal variations, I decided to do a study of a cast. 

The idea is, by concentrating on this one cast, I'd like to gain more. 

I have painted 'Brutus' before, so, I'm interested to see how this time goes. 

Here is a link to the last time I painted this one. 

Work in progress. 16x20 in.
