I can't really decide why I like this one over the others other than the white border makes the color scheme in the main portion stand out. It is clean and bold. It makes me think of modern art pieces one sees at art faires. It definately looks like it should be framed and placed on a wall.
I do love this eclipse series you have created. And I especially like this one because of the background. Photo manipulation in the pattern of the circles is very nice. The whimsy of the ivory circles across the dreamy beauty of Renaissance style landscapes you've created, is quite pleasant. It tweaks one's interest in staying longer to discover shapes and lovely, quiet, tranquil scenes.
