Dragons (Dovah, or Dov plural) are a reptilian race from Akavir that were once widespread throughout Tamriel. Although seeming rather beast-like, they are profoundly intelligent, capable of speech, written language, and comprehending other languages. Their spoken language can be used to cast powerful magic known as Thu'um or Dragon Shouts. They were virtually extinct until 4E 201, when they have resurfaced in Skyrim with the return of Alduin. - Elder Scrolls Wiki
I've been playing Skyrim a lot lately, and during my time playing, I've encountered numerous dragons. Something I noticed is how extremely detailed they actually are. Looking back at my other dragons, they were not accurately detailed. This is an effort to match that level of detail most dragons have, using texture, color, shading, and added features.
