It's not the traditional structure for wyvern wings, as far as I know, but it works, and Red likes this design.
The suit will be a partial, so the wings had no torso to attach to. We agreed that he could just use safety pins to attach the loose bits of the wings to whatever shirt he wears - they're fairly discrete, easy to take on and off, and easily replaceable if one breaks.
The straps between them are really small. I may have to edit that.
