Kimberly, first, your pics are fantastic. I took a quick look only, but was very impressed. Partly because they're good pics, partly because they give more than one perspective on the bag - super useful to the customer who can't pick it up to examine it. And, your shot with the mannequin made sense to me too. Very cool!
Having said that - I expected to see the bag "worn" on a clothed model or mannequin - not the "styled" shot with various other objects. That one was... moderately interesting. I don't know if it's more pinnable because of the other objects - my personal preference is for the one with the mannequin!
I bet you're going to get a lot of different opinions - which may or may not be helpful...!
