Although I agree that the speeder looks a bit AOTC-like I’m not too sure about these people being high society, at least not in the PT sense with Padme/politicians. They look more like gangsters to me. I mean look at the guy at the left of the top picture, he looks like a gangster caricature in alien-form.
Plus, weird looking or not, I’m not going to judge the designs too harshly before I’ve seen them in a more comprehensible context. And those guards/soldiers from the McQuarrie drawings looks pretty cool and OT-like.
