Hi There! First, congrats for getting through the lesson. Here is my critique:

Arrows: The arrows look good. Don’t forget perspective, start large and taper smaller. Try keep it consistent.

Leaves: The leaves look great! I can see you added form to the edges of the leaves. The twist in the leaves looks correct.

Branches: Well done on the branches! Your ellipses changed angle where appropriate and were kept consistent. Your line strokes look confident as well.

Plants: your lines are drawn confidently. Don’t forget texture is drawn using cast shadows (which you did do for most of your forms). Try not to outlines textural forms to create texture.

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