The second is the photo after I'd played with it in Photoshop for a while. I don't remember now exactly what I did, but I know I selected the circle around the top of the palm, then did all the manipulation to the inverse (everything else). Later I added lens flare, which looks like reflections and created the impression the top of the tree was in a bubble.
Palm Bubbles was the first effort to turn this into a quilt. I liked the other-worldly effect of the colors (which are a little off in this picture), but the bubble is too dark and there's not enough contrast to see the stitching for the palm leaves.
In both of these, I like the color and the stitching, but the bubble or circle really isn't a strong element. I'm thinking there will be another incarnation, this time dropping the idea of the bubble, and concentrating on the alien landscape effect through colors and stitching.
