The first two are about as beautiful a shots of police boxes as I've seen. Usually they're blurry and hiding behind a bush in the distance. Here they're center frame and largely unobstructed with some nice period details surrounding them. The last picture is fine too, but the think I really think about is how the walkways, tunnels, and retaining wall in the foreground would be a decent exterior shoot for some futuristic planet. Lovely photos.
