So here are several design ideas I have for my shadow dragons. And I do plan to make characters out of all of them, though that’ll take a while. Originally I had the males have spines going down their necks alongside the quills, but I decided to do the same with some of the females (though all those who don’t have spines and only quills are females as well).

Which head do you like most? You can pick more than one that’s fine. ☺️ Though I should’ve put numbers for each one but I’ll put the order from upper left being #1 to bottom right being #9, the order going horizontally (to make it easier).
Enjoy 😊
