Hello! Your value scale is really good, and your pear looks good, too. I think all you need to do is make the shapes in your drawing match the value scale more. For example, your shadow shape isn’t quite as dark as the second darkest value on your value scale. Your dark mid tone in your drawing isn’t quite as dark as your third darkest value.  My only other thought is to take another look at the shape of the cast shadow. Otherwise, this looks great!
