First, we have a few small ponds. The water is shaded in several colors of blue to give a sense of varying depth. The shore consists of bare dirt/sand and small rocks. On the outer edge is a ring of vegetation taking advantage of the presence of water to grow. The ponds are roughly 5 x 4 inches (130 x 110 mm) in size.
The ponds can be used in a range of scales. Here are some pictures with both 28mm and 15mm miniature figures for a scale comparison.
Lastly, here is a larger terrain piece representing a small lake. This piece is roughly 23 x 11 inches (580 x 280mm).
This photo gives a better view of the slightly textured and gloss finish of the water itself.
