After nine years I figured it time to finally get a new reference sheet, done by the amazing  Isvoc who I can't recommend highly enough!

No real significant changes compared to the old ref really. Wing membranes extend slightly further back and are semi-translucent. General proportions have pretty much changed the same, just with more emphasis on how his various features look from different angles.
Primarily the goal here was to fix some of the issues I had with the old one by having a quick easy reference for his colours and features like the collar, forehead crest/symbol markings and scale patterns and style that tended to be quite varied with what other artists would do. Hopefully this works out well!
