I would move the pine tree near the house up on tile. Based on current positioning and perspective, it looks really odd. That said, what kind of setting are you going for? I agree with Kurt with picking the details you would do if this was your house. I would personally remove one of the hedges, add a chimney, add a bucket or some sort of tool lying around. Also I don't know the context you're going for, but it looks like the house is in the middle of a forest. Maybe replace the mailbox with a well? Lastly the door looks weird: the door is missing the bottom part and the colours on top of the frame look weird.
Otherwise, solid shot. If you feel you can do better, go for it. But with some adjustments, you can make this screen even better, and hopefully to your liking as well.
