I like a more 'natural' look in my tank and that looks a bit 'contrived' and 'artificial' to my eye. Don't get me wrong, it's well done and cool looking. I'd love to see it in 3 to 5 years all mature and with lots of coral and fish. But it's not a look I could live with for that long. But the much more important issue is, what do you think of it?
