It came out really nice. Don't be afraid to go darker on your shadows, it will definitely give your drawing a nice punch. With subjects like that it also helps to turn the picture into black and white so that you can see where the divisions are.

To add to what @pell mentioned, your light source is diffuse, which creates more subtle shadows. The small contrast between lights and darks can make it difficult to pick out the shape of those values. From the image it looks like you possibly have a light source on it, but the room being so bright is what is causing that effect. You could try darkening the room except for one light source and your reference image will be a bit easier to work with.

Nice job getting the shape of the fruit. You're obviously taking your time and observing the model. Your shadows are clean, but you could probably push those darks a little more.
