So FFG posted these (among others we already know) full arts by Amélie Hutt.
Apart from being beautiful, you can see that that first art is very similar in composition to the Tadaka/Kaede art in the Phoenix novella, that was also split in half to be used for the Tadaka card. So maybe this one is also for the Scorpion Novella?
And looking at the sword in the Dragon art... could that be the Ancestral Sword of the Dragon?
