Great work Ged, very macabre surrealism. Like chris, I like the overall color scheme and the visual impact of the green in the tree. I also think the image is in a bit of compositional misalignment. I would try moving the overall framing of the image to the left (picture frame to the right) and maybe place the Owl in front of the (our) left hand side of the lower picture frame. Or just anything to get him off the edge of the comp.
