I added extra cording to the large wings because the space was too large to work with...at least for a design that I want to quickly finish. I'm not sure the filling of the large wing is appropriate for this design. That large space next to the body looks unsightly. I might choose a different filling for the left large wing and see which one I like best...or at least lesson the size of that empty space.
I'm not sure about the small wing either. I might try a different filling on the left and then decided which one looks best.
