This is an interesting topic for me...
Wings have always fascinated me.  I remember 
wishing for wings every time I would throw a 
penny into a fountain.  In my dreams I often have 
wings, and lately I've even been drawing more and 
more characters with them.  ^^;
And there always seems to be something special 
about those types of characters.  Something 
mysterious, solemn and beautiful.  Just look at 
Folken, Sizer (VoH) and Chihaya (Earthian).

Speaking of Earthian, has anyone ever seen a cel 
of them in angel form???

Best Wishes,
