The last one makes it look like they're all on a team called the Wonder Women. I'd prefer a bit more differences between their costumes (for instance, Cassie is an honorary Amazon, so her wearing more contemporary clothes would make sense, and Artemis is a Bana, so she might have full Kevlar body armor in a sleek advanced-Themyscrian-tech sort of way), because as it stands, it'd be easy for them to be indistinguishable from each other. In full-on art, you can tell them apart by the costume details, the physiques, and the face/hair colors, but in crowd scenes, they could easily get lost.
