GEB: Thanks very much, sir! I intend to post as often as I get the opportunity! I'm collecting photos of faces from the "What Do You Look Like" thread and Google images and things. For my job I have a free account with one of Getty's stock image libraries, so I try and collect as many of the good photos as I can.
in2eternity: Thank you! The progress is what I like about your SB too...you can easily see that you improve with each sketch and painting. I'm glad you like the horses...those ended up being some of my favourites too! Could you explain what you mean about the construction of a subject?
