Actually, not really. The vast majority of the available re-textures for dragons are nothing special. They are either simply color adjustments (over-saturated & brightened), or the base texture after it's passed through several filters.
My question is, is anyone working on a true "high-definition/quality" texture replacement for all the various dragons in Skyrim, from standard dragons to Alduin himself? Including the Alpha fix for all the dragon types?
EDIT: The only decent one I've found so far is http://www.skyrimnexus.com/downloads/file.php?id=1154.
