Overall I think that the design 3 best looks like a dragon, perked up ears and a pronounced beard look like extra sets of scales and horns and make Tenki look kinda like dragons are always portrayed with numerous scaly horns stretching out behind the head, though when we talk about the "horns-horns" I like the ones on the design 1, thin at the base and thick after the middle horns look a bit weird to me, the lush hairtuft hides the horns as well but I think thats not really relevant.
