And clothes modifications were always really interesting.
I've bitched at cartoons and comics that have a character with a nine foot wing span, walking around with a trench-coat but no obvious hunchback or lumps.
The other thing I've loves is when the wings aren't material but are spirit wings. Like Jean Grey's Phoenix's wings from X-men. Just how is that manifested? Are they telephathic manifestations of power and move with the power of her mind, or is their sympathetic connection to her shoulder and back muscles?
And then there's the colours of the feathers[ black with blue-red-green highlights, or dove grey with tiny hints of purple and what those colours might mean in terms of pigmentation and race and how they match up with the rest of the humanoid body....
Have I mentioned I have serious wing fetish?
