This is a great place to start! You did a nice job separating the values into shapes and I really appreciate the way you drew out your values on the side of the page. The biggest issue I have here is the reference. This is a lovely photo of a lemon, but the light sources are confusing for this assignment. Lighting the lemon with a single strong light source (like a desk lamp) would be the best way to photograph this. It will help your study and you will get more out of this assignment. Hope this helps. Keep it up 👍
