Recommendations for a Hawkgirl Helmet

[mooproxy]

I'm debating putting together a custom hawkgirl minifigure, but the helmet seems to me to be the most difficult part to figure out. Does anyone have any recommendations for parts, either official or custom which could be used for it? I don't mind doing a bit of modifying of another part for it but my artistic ability is essentially 0 so it'd have to be a relatively simple change.
