Male (background) and female (foreground) variations of Velociraptor mongoliensis. *waves artistic license around*

I have been wanting to paint this since I read an article on feathers having possibly evolved for display, before flight. I liked the idea of a more fluffy crest plumage. The male raptor would be able to hide his bright feathers and only flash them as a territorial display towards other males or a pick-up line with the ladies. While photo reference of raptor skeletons were heavily utilized I'm embarrassingly behind on my dinosaur learnin', so I'm sure I missed something. I wouldn't mind pointers however, so I don't make the same mistakes twice.
