Tree on Rock

Overall I like it, but I feel that the rock (boulder?) in the foreground is too prominent . I'm not sure of what was available above the top of your frame, so you might have had to make a conscious decision between the rock and something worse up above. Perhaps if you were shooting 6x7 or some other non-square format you could have retained the angle of view, while eliminating the heavy gray foreground.

The use of angle is really nice, and the subject stands out from the background quite well. The rear elements are enough in focus to add to the photo, but not draw your attention away from the main subject.
