Mitchell,
I'm NO expert, but my comments are:
- love the foresty part of the image, the crispness, colours and setting
- could raise camera angle to loose a bit more of the foreground rock and get more bush in frame
- shutter speed could have been a tad quicker to capture the water flow a bit clearer
- water flow in centre and extreme right too blurry for my liking
Thanks for including all of your shot settings and it's information I can use for trying something similar.
