This is a value or tonal sketch I did a couple days ago for a landscape painting I am hoping to work on this week. I used a gray toned sketch pad and dark gray and black ink pens, and a white chalk pencil. I would like to try doing this painting primarily with a palette knife.
Below is the reference photo for the painting. I took the photo while in New Hampshire last month. The colors of the reeds and the snow were much more vibrant. I hope I can remember them and reproduce them.
