Starting off with the organic arrows, the exercise is as much about the perspective as it is about the folds, as described here “Mistake: not applying perspective”. You did quite well with understanding how the 2D plane can turn and twist in 3D space, however I would like to see more attempts in pushing the boundries of the 2D paper into the infinite Z axis ???? .

Whereas your organic forms with contour ellipses are pretty good, I can see you are struggling with organic intersections, which is completely natural as it’s not an easy exercise. You have to make sure the width is uniform as otherwise the construction becomes inconsistent. What helped me when doing this exercise is to think of the sausage more as a cylinder with a ball at the each end first, and only then as a sausage.

The reason why I pay attention to this exercise so much is because it’s extremely important in future lessons, especially 4 and 5 where you will use sausages for every construction of an organic shape.

Your texture exercises are very good - you focus on the cast shadows and contours over outlines and explicit drawing.

The form intersections is a quite a difficult one to pull off and you are doing in it quite well too.

All in all, you understood the lesson very well, but I would like to see a few more pages of the following exercises:
