Both her feet are on the wrong leg (Sorry, but how could you screw it up THIS badly?!). Adding "error"-tag.
And yes, she will never be able to dance.

They don't look backwards to me...at worst she has a slim big toe on her right foot and her arch is a little wonky. Color and shading would probably help.

I think your attempt of justification is ridiculous.
Just look at the big toes. That's not a little toe drawn a little bit too big ON BOTH FEET. Those are big toes, no matter how look at it, the artist simply fucked it up. I'm not re-adding the error-tag, to avoid one of those stupid nitpicking wars, but it should be clear for anyone looking at this pic anyway.

..... those feet, I think they should go the other way around..

Before you get all haughty on me, you may want to check the tag history (I didn't remove it). I'm not forcefully attacking your judgment (as you are mine), simply stating that they looked fine to me. That was at around 4AM my time, and my eyes were too tired to notice that her legs were crossed. That or I didn't scroll up far enough. I don't remember. I suppose that explains how the artist made the mistake too.
