Honestly if your proud of your work that's the most important thing! It looks good, the only thing I think would be worth considering is using an additional gradient on the front face, it looks a little flat with just the line and 2 brightest dots on the front, this makes the pear look cut in half; And the shading behind the pear is a bit round and one tone, make sure to use a clear 5 tone gradient and sharpen it like the pear. The lines on the pear look great and sharp, I would experiment with that further if I were you and see how sharp you can make the lines but keep it looking like a pear. Really great job on this!
