The coloration is based on a Cassowary. For reference, I used a Skeleton Diagram by Ivan Iofrida because Scott Hartmann didn't have an Oviraptor skeleton diagram.
I need to do more Oviraptorosaurs! Maybe I'll do Citipati some time. Also, before someone says that its crest is too big, I am aware of this. The crest is mostly Keratin, and only part of it is made of bone.
