I enjoyed the video...very informative, and I love it when folks show the diagram describing the lighting and model placement!!
One thing that struck me, and is just constructive criticism (coming from a total noob mind you), is that the B&W pic you showed, to me...seemed to have an almost plastic, unrealistic look...and you then mentioned you'd used a bit of skin softener.
I wonder what that shot would look like with less skin softening? Maybe do a version with a bit less and post them side by side on this thread?
Anyway, that was the only thing that caught my eye as a little odd looking..but again, enjoy the video and showing the shoot over all!!
