Lovely sunset colors, but that could be said for most of the challenge entries. The color that really grabs me from this shot is actually the teal on the water and how it blends as it goes to the right side of the photo.
The legs do get lost in the black foreground. I think if you had lowered the camera a bit it might have looked a little better.
good colors, but the people are dead center, move to the left or right just a bit...to the right would make them more in the focus of the shot, to the left more an after thought...
I like the saturated colors and I'm a softy for silhouettes. I think if the comoposition were a little more inclusive (More sun and smaller silhouette) it might be even more intriguing.
