Well, your choice looks fine to me. One of my web-cruising things is to constantly save images of currently fashionable celebs and models for quick reference at clothes-shopping time. Just looking over some of the recent ones, it does appear that there is a trend toward wearing either lighter shoes with darker clothes or darker shoes with lighter clothes. The shoe thing is kind of confusing, though, since there seems to be no real rule about color matching-- except, perhaps, that nobody actually matches them.
