Another thing that you might try as well is clear silicone in a tube. Stuff from home repair stores. If you lay out some wax paper, you can the draw beads and play around with the thickness and such. Then when they have dried, you can pull them off and see what looks good for the figure. I have done this in the past to make waterfalls and fountain effects. The scale of the end project will determine the best thing to use. Also take a look at woodland scenic for their water effects product line. Lots of cool stuff there and their tutorials, while mainly for model railroads offer a lot of tips that can be transferred to lots of projects.
