At least once in an artists life, we end up drawings wings on a human or humanoid character. Really, to do so, we should learn to draw wings properly, and learn to draw people. Both things are hard, but society tends to allow more…unreal wings as acceptable. Many times have I cringed at a supposed masterpiece when I gaze upon the insanely impossible and useless wings the author has decided to don their human-looking person.
Of course, it’s all touch-and-go, since there are no real humans with wings (yet?), but still, it’s worth the effort to thing and plan these things better.
