Starting with your arrows, nice work - they flow fluidly through space, carrying a strong sense of movement and energy to them. As they get farther away from us, don't hesitate to allow the zigzagging sections to overlap as that spacing shrinks more and more with perspective. Right now you're compressing that spacing well, but it seems like you may not be entirely keen on allowing them to overlap, which undermines the sense of depth in the scene.

Moving onto your leaves exercise, it feels as though you kind of phoned this one in, leaving a fair bit of room where a few more leaves could have definitely fit in this page. Towards the bottom of the page, you start to show reasonably decent flow to your leaves as they move through space, though I do feel that compared to your arrows, they're definitely somewhat more stiff. Remember that the core of this exercise is to capture not just how these forms sit in space, but also how they move through it as an extension of the wind and air currents that push the leaves through the world. We achieve this by ensuring that in the first step of leaf construction, we draw that flow line with full confidence. I find that adding a little arrowhead helps a great deal, as it reminds me of the kind of motion we apply in the arrow exercise.

Also worth mentioning, you seem to be distracting yourself here by adding form shading to your drawings. This is something we talked about back in lesson 2, in how form shading for no reason other than as decoration is not something we include in our drawings. It's easy for students to mix it up with cast shadows, so be sure to review the material on that page from lesson 2.

You're doing a pretty good job with your branches - although again, lots of empty space left on this page. You've got the segments blending seamlessly into one another, though keep an eye on how there are visible, sharp kinks at each ellipse. We want to give the impression that the branch flows smoothly and continuously, rather than having a series of visible breaks in its flow.

Moving onto your plant constructions, by and large you're applying the principles of construction quite well here. You're drawing large, so as to better engage your spatial reasoning skills, you're drawing through each form (even when there are plenty of leaves and petals), so as to better understand how each one exists individually in space, and you're doing a great job of adhering closely to previous phases of construction when steadily building up further levels of complexity. This construction was especially well done.

The only issue is the one I already mentioned about form shading, as it comes up again at the end of your submission. Form shading is where a surface gets lighter or darker depending on its orientation relative to the light source, and it is generally encountered with a gradual, smooth transition from light to dark. As explained in lesson 2, we can use this as an excuse to include textural information, but simply drawing it for its own sake serves no actual purpose. Cast shadows are a different matter - they fall on other surfaces (rather than the form casting the shadows), and can be very useful in clarifying our drawings.

All in all, you're doing a good job, so I'll go ahead and mark this lesson as complete. Make sure you sort out your understanding of the differences between form shading and cast shadows (and how/where we use them), and make sure that when you do "one page" of an exercise, that you take full advantage of the space afforded to you on that page.
