Either is fine with me. 
I generally only change the shape of a few facial features (lip shape, nose shape, eyebrow shape, face shape, and eye shape) when CC-ing, that usually fits with any art scenes, especially paid ones that are legally forbidden to look like Episode sprites. But I also don’t need art scenes, and only really enjoy them if they’re really good or show something that the Episode sprites can’t.
I think authors can have the best of both worlds with a big disclaimer that says “THERE WILL BE ART SCENES but you can still CC if you want”. If the CC doesn’t match the art scenes and the reader doesn’t care, they don’t care. 
I read Adrenaline having CC’ed so the MC didn’t match the art scenes, and that story is still one of my favourites.
