Decidueye has some interesting concepts in it's design but no thought is put into those designs to make them feel like an actual creature-- as a result you get a smattering of concepts that war against not only each other and the physical limitations of a physical goddamn body. As a result, decidueye's wings clip into a goddamn hammerspace instead of actually fucking folding.
