Why is fierce warrior demon wearing nothing but a metal bikini? Oh, wait. I forgot. Its because a woman's value is judged by how sexually attractive she is. Nevermind how impractical this is for battle. Anatomy is a all wrong too. Where's her neck, and why is one leg longer and thicker then the other?
First, anatomically, the only issues are the angle of the wings, and her head placement (partially how low it is compared to her shoulders and partially the direction it's looking for the swing she's doing). Second, let's take a look at those wings for a second, go ahead, do it. Now look at the size of her body. Assuming she has bones like those of a birds, she wouldn't actually had the strength to wear full body armor and use her flight and agility to the best she could, and because of the way she's build, her agility and maneuverability would be key points to her fighting style. She also wouldn't be able to wear something covering her back since it's covered by huge wings, so giving her a full-plate top wouldn't work either, I will give you that she could have had a flatter plate armor on her chest to cover where her heart would be in case of arrows, but if she's not dodging arrows then she's an idiot anyway. Next, she wouldn't want anything heavy on her lower body either, since it would actually mess up her flight patterns and center of gravity, on top of that, restricting her talons, which I'm sure she'd want to use as an additional attack. It also provides less resistance the less armor she has in case she wants to do flying charges of any sort. Next, since you're calling her a demon, let's focus a bit on lore. Most female demons in any lore actually use their bodies as a weapon, since humans are so quick to "objectify" women and make them nothing but objects of lust, demons actually play on this and use it to their advantage, so a female demon would be more likely to be half naked on the battlefield. Now let's talk about "objectification" in general, because you think it's just done to women. Go ahead and look at video games, ANY video game. Now look at tv shows, ANY tv show, then look at any kind of media. Tell me how many men aren't what you would consider attractive that aren't "old". Go ahead, I'll wait. (the only time this is not okay is when anyone, male or female gets put down because they don't look "good" whether it be because of weight or any other thing, but that's a slightly different subject, even though you did turn around and insult everything that was wrong with her immediately after saying that judging her value on her attraction was wrong, just food for thought) Women aren't the only ones that people use to sell things with their looks, so stop whining and enjoy the eye candy, because it's not going away.
In anatomy, nothing changed from the original stock. Everyone has the right to submit a picture to your liking. In the same way as any other to Express their opinion. You have expressed my point of view, thanks.
