Pretty sure those wings wouldn't be functional either, but...meh. Everything seems purposeful here (this obviously isn't an inexperienced artist making mistakes left and right), so I think there's room for suspension of disbelief.
In this case, yes, I agree. Because this artist has shown she has a firm grasp on anatomy in the past; as in, it's okay for her to break the rules because she knows them. But for less experienced artists who don't quite get how joints work yet, I'd advise them to drop the "it's my style" excuse.
Wow! I love the pose, and expression while biting into the apple, very confident. She holds herself with dignity and respect, just something I noticed. I love the colors! The softer yet warmer hues really work well in this image!
The breasts aren't that visible. As it comes to backgroung it fits well the character.
As I'm already making suggestions, for the next time you could make wings in more appropriate proportions, I know it's fantasy art, but that's just the way I am, I'm a percectionist, I like even fantasy creatured to be designed "properly", wings as big to be able to raise the body in air, etc.
But don't take it too seriously, It doesn't prevent me from liking artworks.
