7 - Nice tones and ripple capture. Could just be the perspective, but a nudge up on the right to 'straighten' may have made this even better in my opinion. Difficult, but just a touch more depth/drama/contrast too perhaps.
I like. Not wholly sold on the metal tonality, as i think it might have been interesting enough in simple black and white: likewise I wonder if you might not have made more of the shapes and patterns within the water. A fine contemplative study nevertheless.
This is a fine shot. I rate it a 4 not because it's a weak composition, but simply because the wide array of approaches in this Free Study compel me to put this on the "less original" side of the coin. Excellent work.
