HOSNAP, those are crazy (from the BMW commercial, right?).
One of the other dA people you linked me to actually reminded me a lot of that commercial, but he might actually have done a better job. XD Those things are insane.
You should know, though, that I am no engineer and I ended up mostly using your Pivoting Pinions and your mockup-thing for the shapes in my wings. Not that I didn't take all your suggestions into consideration (I'm incorporating little details from several of them), I've just sort of fallen in love with your work, and it ended up being my favorite overall 'look.'
I'm nowhere near done, but I'll be posting if they work out.
Thank you for everything!!
