I really like the added colors, richard. I think you still need to get darker on that right side of the branch. Remember that you are trying to get 9 values. Right now your branch is mostly midtones. Keep the ideally toned cylinder in your head, and try to erase out some highlight about a 1/4 of the way in from the left. And build up some darker tones on the right side of the branch, gradually fading out toward the highlight. You could work on that cast shadow a bit more by trying to get that dark line to more gradually fade out to the white of the paper. Right now that dark line ends fairly abruptly. Keep going, Richard. You are doing great!
