I have to say, I think these dragons are absolutely gorgeous. I also love the Xenowyrms and the Spirit Ward Dragons (they would have made great Halloween dragons, but I'm glad they're just regular, so we can get more of them during the year! I love that they change colors at night!). I think the spriters have been doing an excellent job, and whoever is selecting the releases (I'm assuming TJ), has been doing a good job as well.
I can only wish that the Xenowyrms were more common because of all of the variants, but that's a small regret. And I wish these weren't so popular, because I'd love to be able to snag one of the bronze variants right now.
