Woohoo, first pear!! You've done a good job with having distinct value and nice sharp edges! I would suggest lightening up the lighter halftone around the highlights just a tad. Also, keep in mind how the edges of each value are sloping, and try to follow the direction and planes of the pear. It'll give the pear more volume and make it feel less flat. I lined the one that I felt stuck out, since it was kind of a convex line instead of concave. Keep up the great work!!
