Hi There! Hope I’m not too late in giving some feedback. Here is my critique:

Arrows: Your lines are confident. Shading is shown on the correct bends. You kept good proportion and followed foreshortening techniques.

Leaves: The leaves look good. You could have experimented a bit more in twisting the leaves. Well done on breaking the silhouette of the forms.

Branches: Your branches show confident lines and connect well between ellipses. The ellipses show a gradual change in angle. Well done.

Plants: Well done on your plants! Your construction looks great. Again, some of the leaves could have been a bit more twisted to add a more dynamic feel to the plant.

Else Very well done on this exercise. Of course, keep doing Lesson 1 warmups as you are heading through the next lessons.
