Wow, this image really attracted my attention when i first saw it. The contrasts of green and brown are so strong and the fact that the sun is seeping through really gives an illuminating feel and really draws you're attention to it.
Now, i don't know where you live and if this spot was easy for you to find, but i love it when someone really goes out their way to find that special area to take pictures of, and i love this because its in a forest which looks so, un-touched and just, wow!
The composition is really amazing, there is a good quanity of the water and the trees in the background with the focus obviously on the water, i think 1 second shutterspeed is exactly what i would have used, really good, and i really do love the composition. Iso could posibly be slightly higher, but never the less, i love it, very original. And leaves an amazing impact, i really love this, Congratulations
