It really looks great, I agree with Marc, but may I be a nag? It might be the sunlight streaming into my workspace here, but the front woody area seems very dark and a bit 'even' to me. It lacks some focal point, something to attract your attention, so to speak. A single rocky outcrop, a pile of boulders, a little stream or lake, a cluster of differently colored shrubs/trees. Mind you, I do like the overall image, it looks very natural and realistic!
