Here are my three attempts. I have a problem with quite a few things, such as knowing where to start, confidence in my lines, and proportion. Stan’s demonstration was very helpful. I will now try these drawings again and try for improvement in each of these areas.
I have tried again with the pears, but I really struggle with seeing the darkest value on the fruit. I would use only the lightest dark and the 3 light values. I guess I need to train my eyes to see what is really there. I will keep trying.
