Do any of you have favorite tweaks you've made to your sets? Little re-arrangements you've made to your sets that don't necessarily qualify as revamps or mocs, whose only purpose is to make them "feel" better? For an example, I submit this "Mermaid-tail" configuration for Gali's fins. Her instructions put two axles on only one of the fins, and they pin together perfectly to make one fluke she poses very gracefully in this configuration, and it gives her another layer of complexity. What tweaks have you all made to your favorite sets?
