Very nice Steve.
One (personal) observation: For portraiture I like a dark background. For an "advertising action" shot like this, I kind of think that a brighter background would work better. Maybe just me.
But regardless, your work on the model's pose and her lighting is fabulous - very pleasing!
my husband would buy 2! and a pair of the jeans she's wearing! I personally love the shot with the dark background, but am not an expert and agree that for use as an ad brighter would be better (i think don hit it right on) - also maybe show more of the bag (if that's what you're trying to sell ) her arm is cutting across the "victoria logo" - I know, I bought one for my 23yr old supermodel ! But as a shot (forget the bag) it's just beautiful. Oh to be young again!!
