Very nice placement for your shot, it is deserved!!!
I love the details that you have captured here, sharp , clean and clear. You DOF is good, would have liked to have seen it without the heel of the other shoe in the shot. Did you try it with just the front shoe, that would have been interesting.
The heel is a little blown out, so watch out for lighting. There is also a bump of white near the front of the shoe that is distracting. What is the white plastic looking thing on her foot? Is that part of the shoe?? It almost seems out of place with all the intricate details that you have with the beading etc.
Overal, a very pleasing shoe and foot, well done!!
Excellent lighting in my opinion. I like the pose and presentation of the subject, but I think additional attention to the composition would help...a bit to centered for me with the heel of the back shoe "sticking out". The detail of the shoe is fantastic, good choice for the challenge. 6
