Yes, it does look nice! I also think the redish colored fence works well.
We installed a Japanese rock garden at out shop. Even bought a book on the subject, but in the end just went for it. However, one thing I do remember reading was that the walkways should add the illusion of depth. Basically, you use a very large stepping stone up close, with progressively smaller stones as you move away. The trick is to fool the eye into seeing more distance than is actually there!
Kind Regards,
