SUGGESTIONS! (Not obligated ofc <3):
Finned Cobra hood? Like the earfins/spine ridge but on the head and dropping down the neck?
...Actual cobra hood? :)
Decorations? Earrings, horn clasps, wristbands, bangles, wing holes, torn wings, scars?
Maybe more body types like Skeletons (if its not too difficult), lung dragon, and lindwyrms?
Another pair of arms instead of wings? (like.. not webbed)
Maybe a way to increase the length of the tail/neck/body instead of new bodies, and the platform follows the path of the legs?
No pressure of course!! This is such a cute creator! I'd love to play a game with this style of dragon character, even if it was just a little explorer type.
