Yes, you could slap some blue paint on your face and say you're a Dunmer, but other cosplayers go way, way beyond that.
This Alduin cosplay from Sedulous Studios took a month and a half to build, and the results shocked and amazed attendees at the recent DragonCon 2014. It might cut down the awe a bit to see Alduin scratched behind the ears and called a "good dragon," though.
The photo below from Sedulous Studios' Facebook page shows the might dragon in the course of construction, and the clever elements that went into building its "skeleton."
