Gary,
The pictures and the layouts are wonderful! I'll take a closer look later but did you use an on camera flash? I was wondering what difference it would have made if the flash was used off camera and either held to the left or right of the subject to get some side shadow. I was thinking of giving that a try myself maybe dragging my son along so he can hold the flash as my arms are not long enough. Can you recall what fStop, ISO and speed you used?
Thanks for sharing them with us.
