The only place I see where anything may be missing is she has 2 symmetrical holes in her forehead that may be missing something to go in them. Or they may be part of the design. I tried to piece it together so I could see how it connects.
The last 2 pics show the head placement and the wing going in. The side I photographed attaches by 2 pond, but the other wing has no pins or holes. It appears to just glue on. It does line up with the grooves on her head so you can see where it's supposed to attach. This item is in the category "Toys & Hobbies\Models & Kits\Figures".
