Great link Paul! Cheers for that. That whole site is very useful!
I've started work on a couple of other pieces. I've been trying to work out how to do a waterfall and I've came across some of our railway modeller colleagues techniques. To create realistic water they seem to use bathroom silicon sealer. You need something the silicon doesn't stick to. I used a bit of plastic card. You just apply it in vertical lines. Once that's done (while it's still wet) run a tooth pick down its length to rough it up. I also added some wee bits of white silicon with the toothpick, to look like frothy water.

It's going to be attached to this...

I've also started the sword in the stone piece. The poles are going to be lit torches when I'm finished.
