Very cute
But it seems a bit dark to me, just tiny bit. Especially compared to the moon. I feel it might be stealing attention from the hedgehog.
Concerning the leaves... they fee a bitl weird an unnatural or artificial to me. They fall straight down, I dont think leaves fall this way. It is just a gut feeling.. They blend a bit with the background since they have exact same pattern as branches on the background trees. Light might be also a bit off since they are quite close to the lantern, but quite dark.
EDIT: my contrast on was too low and it was way darker than it really is, sorrry
