It's actually a bit more about observation take a look at the birds and reason a little with proportions and logic.... there are many tutorials and guides/references that help, I personally like this one: libertades.deviantart.com/art/…
Yeah, that tutorial makes a lot of sense. Certainly makes me wish I had more artistic talent than the average potato so I could draw a few of the winged characters floating about in my headspace... However, what occurs to me is that they might not be her wings at all, just parts of the armor. In which case, they could be as anatomically incorrect as aesthetics call for, since they could be balanced by gyroscopes and engines. Now, were this not sci-fi, I'd probably defer to your bird-wing wisdom. But we all know what the majority of sci-fi does to anatomy.
I understand, sounds like a reasonable explanation, if that's the case then I guess it's a well placed pair of wings it just worried me that the anatomy was going to be always ignored like this since I'm a very passionate bird lover, but you're right about sci-fi, though sometimes sci-fi can get along with reality every now and then it's a nice idea though that the wings might be more of a mechanical thing, though if that was the case, I honestly think -though it's also a personal thought- that there should be more elaboration for them, maybe not anatomically correct like animal's but right enough to make all gears work just like a robotic arm is perfectly done.
Again just stating what I believe, I still think a good job was made with the illustration
