Original video clip was blurry, but I like the composition, so continued to fiddle with it.
Played with increasing saturation to deepen the color, burned in the clouds and lightened and erased the crabgrass spots.
Enhanced the texture of the stonework and shadows of tree by tweaking curves and applying watercolor and paint daubs effects.
Desaturated completely, and tried sepia tone through curves adjusment for pen and ink look.
Ended up softening the daubed watercolor effect.
