It's not real obvious how to get that atmospheric effect with acrylics. This is one way I stumbled on. Paint the picture in a straight forward manner. Overall glaze with red, let dry. Overall glaze with yellow, let dry. With Golden Fluid Zinc White glaze selectively over the sky, water, mountians. Then darkened the reflection of the trees with a dark green glaze.
