Nice silhouettes and interesting composition. The colours of the sky are vivid, but something about the way you've framed this makes it feel a bit flat, to me. I don't thinke the negative space quite works the way it should. It makes the trees feel like an afterthought, rather than being an intentional element.
I'd love to see some experiments with different crops!
Very pretty. Definately naturally occuring. i like the silhouetted trees against that sky. What wonderful colors. The angle and framing/cropping are great! I think the focus is a little soft, but don't quote me on that , cause I've never really seen these trees before, so that might just be how they look. Otherwise very nice. Good luck in the challenge.
challenge met. wonderful colors in the sky, i like how they intensify just where the palmtree sillhouettes are. i would like to see more of the trees, but i suspect you'd see the "hand of man" somewhere if you included more at the bottom .... good use of negative space.
