This piece is from the Stilla nation. It was found in the Old Crown tomb. It is a head dress intended only for burial. It was assembled from thin pieces of gold sheet. The ornaments suggest wings or feathers, although the actual purpose is not known.
Definitely just find reference pictures on Pinterest or something (you can check out my acc my at is greenteaxbabe I have a drawing references board) And get the sizing correct in reference to everything else in the picture. Good work tho keep at it!! <3
