You chose a beautiful spot to pose. But the problem with beautiful spots is that they rarely look good in photos. And the things that make them beautiful are the things one must generally eschew from portraits because the eat up space and draw the attention from the subject. So that log you carefully worked into the photo, that is a beautiful and photogenic log. And for precisely this reason it should be excluded from the photo. Same thing goes for those rocks, especially the one sticking out of your back. As for the lighting, it is flat on the subject's face. This is generally the least flattering lighting since it tends to wash out features. Also it makes people squint. And with a digital camera especially, strong sunlight is a bad idea for almost any photo since the detectors do not have the latitude of film. This means that significant areas of the photo may be washed out and large areas black. Sometimes this is the effect you want, but it doesn't work to do this to the subject but not the background.
I like the stump. And I like the pose. I'm a maniac about cropping and would crop on all sides.
Keep trying.
I like to imagine myself as a good photographer, but I already imagine I'm a middling judge of photos.
