Sweet river

First off let me start by saying wonderful colors. I don't think you could have picked a better time of year to take this shot. The deep browns of the water and light yellows of the trees give the photo a definite mood.

You certainly have a photographic eye

- However it appears the photo is slightly over exposed (viewing on a calibrated monitor) There is also slight camera shake, you can tell the photo isn't as sharp as it could be. I have also noticed in the camera data that you used an aperture of f/22. While it is true this will give the most 'depth of field' for sharpness throughout the photo an aperture this small causes diffraction. (meaning light bounces around inside the lens before it hits your cameras image sensor) This will definitely hurt image quality. To be on the safe side your best bet for a diffraction limited aperture setting would be f/16; but this obviously depends situation to situation. Finally I would add that resizing your photo to 1024 pixels (instead of a massive 4912x3264) is a technique called 'downsampling' short answer it makes your pictures look sharper when viewing on the web.

As I stated before great photographic eye! just got to get that technique and technical stuff down and you'll be pumping out great works for sure!
