They both look good, but the first one with the dark sky definitely has the vibe going for it more. His beastly form won't be as distinguishable, but I don't think that's a problem, to be honest as there is an air of mystery about his true form anyway since he is presented in darkness when shown most of the time in the comic anyway. I think the most important feature for being able to see him is his eyes and beak (and you got that) having the rest blend into darkness feels legit
.
The title also sticks out way better on the darkness where the glow can add just a hint of magic to it.
Fantastic job Rose!!!
