The issue is never correct anatomy or realism. The issue is focus and intent.
If your art style is stylised and you bend anatomy to create a cooler image that is entirely ok. If you simply have a different style that isn’t hyper-real, then actually that’s great…because I’ve never been a big fan of the trend for Hitch-style hyper-realism. It’s great when done right, and it fits the series…but not on everything, please?
But if you’re bending the limits of human anatomy just so you can get a female character’s bottom and breasts on the page, then that’s not okay. If your intention is to arouse the viewer, if the focus is purely on the character’s existence as a sexual being, then that’s not on.
I’m not saying there should never be any sexiness in comic art. Not at all. But there’s a time and a place…and that time is not all the time…and that place is not everywhere.
So let’s not criticise comic art simply because it is not 100% anatomically correct all the time and doesn’t conform to the bounds of physical reality…because, quite frankly, super hero comics would be kinda’ boring if they slavishly kept within the bounds of reality. Instead, let’s look at the intent and the focus of a piece of art. Is it presenting the character as an object, or as a person?
