You are almost there Marijke! On the top nut part of the acorn you could use more range of tones. With a kneaded erasure, I would lift some of the pencil flanking the highlight. I would also eliminate the white line in the dark area on the right. If that is a reflected light it is not in right place and I would not worry about including it yet. With the lower cap part of the acorn, the darkest area is the left side, which is opposite than your top and what it should be. Since the left side of the acorn is closest to your light source, the right side should be the darkest area as you did on the top portion. Most of the cap is all the same tone so when you make the correction of switching the position of the dark area also work on having a range of tones and don’t forget your highlight. As I said, you are almost there!
