After thinking about it for a while, decided to give Skulla wings. As a shapeshifter and mostly just for my convenience, they don't need to be there constantly. In fact he prefers them not to be there. Salamander's wings are now optionally, but he actually prefers them to be out.

Wings on a western dragon just always seemed right, and he's very heavily based on Sala's design, so I don't know why he didn't have wings before. Same structure and build, with the tops and "fingers" of the wings being his primary medium blue color, and the underside/webbing being his underbelly secondary color, aqua.
