This looks amazing!!! I think you've captured the gestures really well. In the future, I think you should try going for even cleaner lines, don't go over the same area twice, especially with this kind of textured paper as it'll make the sketch look kind of messy. You can even think to be even more expressive with your lines. Overall you did a wonderful job just try to push the boundaries of what can be done with your work even more.

Firstly, I think you did a wonderful job of simplifying the values of the shadows. The cast shadow from the pear onto the fabric is clearly differentiated from the shadows on the pear itself helping us make sense of where the pear is and how it is interacting with the light source. One issue that I think will really transform your drawing , when fixed, is capturing the curve of the pear in the middle. I am talking about the curve that differentiates the top and bottom of the pear (look at screenshot 1). To do that try to add the different values of the shadows in that specific area almost outlining the curve (look at screenshot 2). You can even try thinking of the top and bottom parts of the pear as two separate shapes that need to be outlined for us to make better sense of the pear's form and position. ( screenshot 3) Your final image should look similar to screenshot 4 and even better as this was a quick sketch. Hope this helps!
