A nice division between the falls, the basalt columns at the top and the riot of green and splashing water at the bottom. Wish the foreground were in sharper focus - the details of the leaves would make a nice contrast the the misty background of the falls. you must have used a longer exposure to blur the movement of the falls (works nicely!) but the leaves must have been blowing a bit? Lovely green color - Iceland in the summer is beautiful!
Challenge: 10 very beautiful location.
Compostion: 7 The waterfall is too centered a little to the left or right would have given more green giving a more vibrant color. This would have also removed some of the lens blur in the right corner of the stream.
Technical: 8 I can't tell if this is a snap shot or a timed shot. The stream is telling me snap shot but the falls is showing me a timed shot due to the movment of water.
Creativity: 10 Waterfalls are just so appealing to photography.
Overall:9
Waterfalls always give us such a serene beauty and feeling of calmness, I particularly like this one because I think I've actually been there if it's in Iceland
