For this image, I used a variety of my favorite effects: tritone, blur overlay, and a vignette. I also added several render cloud overlays and a little bit of noise. Any C&C are welcome!
I like it Christopher! Every time I would look at this tree to decide what to do, I got an ominous feeling. It reminded me of the scary trees in an Enchanted Forest story I read as a kid. Your rendition is closest to what I was feeling.
