In my opinion it lacks a central attention point. There are several elements fighting for attention: the big tree, the trees on the left, the tree on the right, the path, the rock, the grass, the leaves; but sadly enough, none of those elements is emphasized enough to really grab the attention... I'm afraid that this will cause the whole image to go relatively unnoticed. Try to find a central and strong focus point in your composition (by 'central' I don't mean that it has to be 'centered'), with the shapes and lines around it merely serving to strengthen the attention on, and lead the viewer's eye to the main subject. Easier said than done... I know. An image with a strong main subject will usually attract more attention and approval. Wish I could go further in detail, but I have to run to work just now... Good luck!
