Tried paying more attention to values, but ended up making more contrast than the original, thought it looked better that way. I know the field should be a little darker to be more accurate using the gray scale. But to me it seemed lighter because it is yellow. I have not figured out how to draw clouds with pencil, without all the pencil strokes showing, maybe shade the whole sky one tone, then lighten the clouds shapes with the eraser?
This is a small drawing for me, 4×5 and it was hard to make the lines a good size especially in the grass, usually I work with a bigger area. As usual the contrast is greater in the photo than in the drawing.
