Dragon Pale Tree-- Concept

I just recently saw a lot of theories that the Pale Tree was a dragon or would somehow ascend to become a dragon. While I don't believe she's a dragon (she's basically a purified Blighting Tree, right?) I think the idea of her replacing Mordremoth is an interesting idea. So, I ended up drawing a concept of what she would look like. My inspiration/reference was mostly just the Avatar of the Pale Tree, but I also took some inspiration from Monarch Butterflies on the underside of the wings (which you can't really see a lot here, but... just imagine!)

I wanted her too look elegant and flowing, to oppose Mordremoth's much harsher and stiff look.
