Hi Margaret- you are off to a good start, but there are a number of areas to revisit. Like how well you are doing with shading a sphere, you want to have the same smooth transitions of tones on the cylinders. You have lost the highlight, which is easy to correct. Be sure to have them be consistent in placement. On the vertical cylinders there is the dark stripe on the right without the desired smooth, seamless transition of tones. The majority of tones on all the cylinders are too similar and missing the range needed to convey the cylinder’s form. With your light source coming from the left, there would not be a shadow on the left side of the horizontal cylinders where they meet the vertical cylinders. They should be on the right side of the horizontal cylinders because the vertical cylinders would be casting a shadow on them. All of this is an easy fix. Setting up a model using household items like pencils, chopsticks, etc, with the appropriate lighting can be a great reference to help you visualize what you are trying to achieve.
