Comment on Dragon Wing Tutorial by NakaseArt

Have to note that the propatagium (the "extra" sail between the wrist and the shoulder) is /not/ optional. It serves to give the wing its aerodynamic shape, generates a lot of lift, and, at least in birds, houses the ligament that holds the wing fixed when it's fully open. cdn.tutsplus.com/vector/upload…

Yeah, this is a made up creature, it's not supposed to be realistic yada yada, but just FYI.
