Heh - the palette started off with neat and orderly ranges, but by the end I was repurposing colours and adding in intermediate shades all over the place. It ended up as quite the mess :-)

A decent palette-reordering tool is now high on my to-do list when I'm next hacking about in my paint program!

Very cool take on the challenge! I like how you can see the motion of the water on the surface.

Nice palette. Love the water in the first, the flowers in the second and the fruit in the third.
