Organic Arrows

Your arrows are smooth & flow through space almost well but sometimes their edges are not overlapping each other. Make sure you overlap them when doing them in your warm ups.

I see that you've done lineweight near the curves, good work. Just don't slowly trace the previous mark as that would result in wobbly lines.

Leaves

Your leaves are drawn confidently & follows the flow line most of the time. Also good work on folded leaves, you can work on improving where you apply lineweight but overall nice work.

Branches

Your branches have ellipses perpendicular to their minor axis. You'll have much easier time on these branches if you place an ellipse where the flow line have extreme or sudden curves.

The fork on these branches are not following the instructions, see https://drawabox.com/lesson/3/2/forking

Plants

Your plant drawings are really good.

Sometimes parts of plants are not enclosed in it's planned ellipse, it's a decision you've to make either make a new ellipse if you can't achieve your goals with the previous one or change your plant to meet the end of planned ellipse.

Good work on petals of these flowers, they've nice flow line just like your leaves.

Shadow casting done on the plants are kept to minimum, so they don't over shadow the construction themselves, good work.

Overall you've follow the lesson instructions for most part but it seems you misread the homework assignment as it is 8 filled pages of plant drawings rather than 8 plant drawings.
