I like the composition and line of the tree. It really draws you eye in to the upper right of the photo. The focus, however is soft in the leaves so I don't really know where to go with my eyes. Because the tree is so dark I would really try to get the leaves in focus and let a slightly blurry tree lead your eye into the world of color in the sky.
Great image. The horizon is tilted a little bit to the left, but I like the compositional element of the figure on the wall
I know it is more difficult with a zoom lens, but I was hoping to see a broad depth of field capture on this image when I sent you over to the picnic bench. Ideally, a narrow aperture (F22) would allow the leaves and background to be in focus. That said, if you were going for a narrow depth of field, I would shift the focus into the cluster of leaves in the immediate foreground along the seam of the table.
