The most notable addition is the scalemail along the back of each dragon. The aluminum scales were an interesting change of pace with learning how to incorporate these directly into the fabric of the piece. I tried several different ways of threading my stitches into the scales before finding a way to get these to lie uniformly across both sides of the spine.
The second added touch was changing the boning on the wings to incorporate pipe cleaners. These give it a much more posable adaptation compared to the tubed boning I'd used before, and the experience with the wire is a great cross-skill that I can use in projects down the line.
