IMHO, I am not keen on any of them. Do you have a dark forest green or dark maroon or black? Just try some more colors, even a midnight blue would be nice w/ the rainbow geese. The brown tones seem to over power the other colors in my old eyes
.
If I had to choose one of these it would be the third one, it allows the geese to fly!
peace
EDIT: I also like the idea of a grey sky, but a dark one!
