This is a great drawing! It's actually pretty creepy. Looking at some other stuff you've made, you seem to be known for that kind of stuff. The tree just looks so powerful in this. It's like some bizarre case of conjoined twins. I thought that was a cat at first, but it's a rabbit.
I've never seen a black rabbit before. I just now notice the noose. It seems like this was inspired by "Scary Stories To Tell In The Dark". Those have been popular with creepypasta lately. The artwork, I mean.
