The positioning of the bridge is really crucial here. The composition of the background forest moves the eye to the right of the picture, as does the bend in the creek. I think that should be balanced by moving the bridge slightly so that it starts further up on the left bank and balances the composition. You might want change the camera angle slightly after this to center it on the bridge. The strength in this picture lies in the composition, the balance between the background, the creek and the bridge. Some work here will result in a very pleasing picture, no doubt.
