Maybe try working on a more neutral background, it is very hard to judge value relationships when working against pure white. Try blocking in the background of the apple too so that you aren't working in a vacuum. Judging the the value difference between the background and the edges of the apple will help your ability to percieve all the stuff happening within the shape more accurately, especially if you are working from life. Remember that everything is relative!
