I like what you have here, Richard. I also appreciate the difficulty in getting this much done in an hour and a half (I'm barely finished applying values at that point
).
On a side note, most of the sessions I've attended devote about the first 10-20 minutes on quick one to five minute poses, and then twenty minute poses, with one 30+ minute pose to end the session. It's a little frustrating to start on something but never have time to finish it, or at least address some of the shortcomings you see in the painting. Hats off to you for getting this much completed.
