This is a small body of water in Ohio County, Indiana. To do a lake picture you draw a horizon line, then put in the features above it, like the trees and sky. Next, you do a mirror image of them below. There are ripples in water, so just paint small white streaks across the reflected objects. Even better, rub your finger across them to give a distortion that waves or ripples would make. On trunks of trees put in a light side and a shadow side to give depth and shape.
