I love the shoe. It's drawn very well and agree that it can stand on it's own. I don't get the thought bubble with the foot really. Not sure if the shoe wants the foot, doesn't want the foot (maybe a big X over the foot in the thought bubble would work then). Or maybe instead it should be thinking of a pretty womens pump it met in the closet.
I agree that the style in the shoe is very nice, I'd just like to see your next subs worked more on the concept department. Good luck and keep subbing!
