Starting with your arrows, these are looking great. You've drawn them both with a great sense of confidence to help convey the fluidity with which they move through space, as well as a good sense for foreshortening, compressing the space between the zigzagging sections to better convey the depth in the scene. That confidence and fluidity carries forward nicely into the leaves, where you're doing a good job of not only establishing how they each sit statically in 3D space, but also how they move through the space they occupy.

On top of this, you're also handling the addition of edge detail with individual marks, one at a time - as well as tackling more complex leaf structures - very well. You clearly paid a lot of attention to the instructions.

Continuing onto your branches, your work here is similarly well done, although do be sure to extend each edge segment fully halfway to the next ellipse, as explained here. Currently you're falling a little short in that regard. This is important to achieve a smoother and more seamless transition from one to the next.

Moving onto your plant constructions, by and large your work continues to be solid, though there are a couple of small things I want to call out:

  • Be careful when it comes to adding edge detail in cases like this. Here you're falling more into zigzagging your edge detail, which results in a weaker relationship between the phases of construction, and thus the solidity of the earlier, simpler phases, does not carry over as you increase complexity.

  • As an extension of the previous point, avoid redrawing the entirety of a given leaf when adding edge detail, as well as increasing the thickness of your lines from one step to the next. Each step of construction merely builds off the last - it is not intended to outright replace it. Increasing the thickness of your lines can put you in more of a mindset of redrawing the entire thing. Line weight itself is something we add in its own pass towards the end of the process, and even there, we're focusing specifically on the localized areas where overlaps occur between forms, as shown here with these overlapping leaves.

  • When constructing a cylindrical structure like a flower pot or vase, like in this drawing, be sure to do so around a central minor axis line. This will help you in aligning all the various ellipses you might use to establish its structure.

Aside from that, you're making solid progress, and are applying the instructions for this lesson well. I'll go ahead and mark this lesson as complete.
