So far I'm perferring this style of eye and proportions however it won't be possible to do some of the subtle eye movements that a larger eye with a pupil could do, but most of my action can be shown with a turn of the head or a body movement so I shall see how this applies to my next animatic.
I also have a sheet of new Spirit ideas, looking at waving motion and wave-like symbols to tie-in with the oak leaves. I did some rough keys of a swaying and morphing tail that swirls and breaks apart like water, this could help sell the mystical 'spirit-ness' of my creature. I'll be examining spirits from Japanese video games next to see how I can visually show this creature as something Spiritual, but not like a ghost and still having animal qualities. From my research so far, I have found Japanese folklore to be rich with animal spirits/Gods that are abstracted in some way, while Celtic mythology appears too dark and realistic for now.
