It’s usually the same basic things from each species: horns, ears, and tail. Different species may have some unique things. Like shift spades have a few extra spikes on their head and rear.

Even if a dragon does have wings, they aren’t usually out due to inconvenience and being ineffective. Their world is completely use to dragons and other mythical creatures. So for one to shift into a full grown dragon in a parking lot, is completely normal.

Most dragons can control what features they allow to shift, claws for quick opening, tail for balance, etc. They rarely shift completely human, being a dragon, they are quite proud creatures. They keep horns and tails out to show species and status. Some species are just considered more superior to some, and individuals more superior to others. Hierarchy is based on power and physical features like horns or shape of tail.
