Watchtower Of Orodruin

Everywhere you look at this scrappy watchtower by Tim Schwalfenberg you'll see two things: A very interesting technique, and something unconventional. From the craggy brickwork at the base of the tower, to the cobbled railing at the top, and from the uneven stairs on the left to the boulder rock work on the right, it's amazing. I have to admit I think this would probably give me fits though, it looks so fragile I wouldn't want to stand anywhere near it while simultaneously needing to get a good close look at it.
