I think you can download a demo version of Rhino, I haven't used it myself, but I agree about the mess of modelling in Bryce. Your WIP seems to want a waterfall to the left. It looks like there is a channel, but I can't tell if there is water. If the floor/ground is also water, i think you are going to have to do something to make that more clear. I like the reflections in it, though. Perhaps a small boat floating through your archway? Or a plane/spacecraft/bird flying through? I think the terrains turned out really well. Lin
