Of course, if you'd rather go the natural route, it's hard to get a more natural water feature than a waterfall. If you have the space, try a massive waterfall with multiple levels …
love the brick/stone work and combo with cedar, excellent colors, but the banister and columns are disasters we'd like to avoid (namely lack of harmony, general incongruity)
Love the waterfall from the second story... I also like that it is broken into several falls ... for both beauty and splash control. Hmmm,... and the stream at the bottom has my imaginatiobn going tool
