Standard materials. Kato polyclay over armature, some human hair for eyelashes, reclaimed mohair, clear resin for wings, icicles and ice. Wings are fully removable. Whole piece, including wings, is about 11" high. If the chick was standing, she'd be a little under 6" tall.
I just love how it is a silhouette but that you can still see some details!
Excellent done!
