Nice, but the inside lighting on the left hand one is not right. The others look lit from within by the orbs, the left hand one looks like it's lit from the outside (too much overlap at the top of the curve)

All of the beacons have been duplicated from the first one, I thik it may have to do with the angle.

I do like this... they remind me of sculpture from the 60's. I would have preferred some other surface besides water as the base, simply because you see that so often in Bryce and it has become a bit cliche'd to me. But it's no big deal, I have done the same...

Very good. I like how the reflections on the water glow.
