I love the the girl/witch with pale pink streaks in her hair. Is she a real person or CGI?
The unfocused background draws your attention to the little details - (what appear at first to be) flowers and a spiderweb.
I thought the bright lights around the latern were just that, light - if you look closer, there actually dragonflies as well as the purple light shining at the end of the knot in her dress.
I'm not 100% sure what those purple creatures in the right lower corner which I thought were flowers are. They look like butterflies to me.
The cover makes me think of halloween. A magical and mystical day.
