Peter,
I've spent some time studying the photographs, and can see that you've given these models the attention they deserve. I haven't studied them to find fault, but rather, to try and learn your approach in achieving such success. In my mind, I'm wondering if I could mimic your approaches to garner equal result, or if I would change anything.
No doubt, this is fine modeling. I'm often surprised that so few on this site are compelled to lend comment toward such wonderful efforts... that's just the way it is. On the other hand, I'm positive that viewers leave with a sense of awh, after taking in this type of craftmanship.
