the boots on the right variant read a lot more visually clearly due to the increased contrast. the 'glowing eye' doesn't read, so i'd recommend changing the facial area entirely and either adding the indication of a mouth with the eyes obscured entirely(spooky) or putting the whole face even more in shadow. i think maybe the eye doesn't read as an eye because it appears too low on the face.

i really dig the dusty red highlight colour on the cloak, but i feel like you could bump the saturation of the shadow colour up a bit and it might seem less visually muddy.

good overall!! keep it up!
