Not much a tree anymore but then again, that was my problem with it in the first place. First I made a border around the whole thing and cloned in areas along the sides to expand the bottom part of the image. Applied Nik Effects plugin, midnight sepia for the color and then used fm sampler plugin to make a new effect, changed blend mode to overlay and merged layers. Then used the Kalidescope effect and came up with this. Dont know what it would be good for but I think it was a neat design
