I have one in the middle of my residential area. I also have a heart shaped pond that was part of my original map and I just put bamboo trees around. I only have one picture on hand though, so sorry that it doesn't show the whole pond
One is on the 3rd level cliff, and it is a part of bamboo grove/garden/pond viewing pond area. Relaxing.
The other is BIG and on the ground level. It has a bunch of tiny islands with items on it (star frags/insect models/candles/etc) and a leaping path across it.

Oh, I have that pond too, I thought about reshaping it into something else but I'm scared of ruining it. It's interesting to see what other people did with the same starting layout tho.
