Starting with your arrows, very nice work - you're drawing them with a ton of confidence, which really helps to push the sense of fluidity with which they move through all three dimensions of the world. This carries over well into your leaves, capturing both how they sit statically in 3D space as well as how they move through the space they occupy. That said, I did notice that you're a bit loose when adding edge detail, with a tendency to zigzag lines back and forth across the existing edge, which as explained here should be avoided, due to its tendency to produce weaker relationships between the phases of construction.

In addition to this, I'd strongly recommend not drawing earlier phases of construction with a fainter line and later ones with a thicker stroke, as this is going to encourage you to approach construction as though you're redrawing everything at every step. Instead, we're simply building upon the existing structure, modifying what's already there at each stage. There are things that simply won't need alteration, and therefore the marks that defined them from the start should be able to stand for themselves when you're done, without being redrawn or traced over needlessly.

Continuing onto the branches exercise, it appears you may have forgotten to include it here, so you will need to provide that before I can mark the lesson as complete.

That said, your plant constructions are by and large looking quite well done. I have just a few quick points to call out:

• For your potato plant demo, it seems that you didn't follow the demonstration in its entirety, when it comes to the filled areas of solid black. The demo filled a particular area of the negative space between the thicker area of foliage because it was thick enough to cover all of the dirt beneath it with shadow. In yours however, you lack the other cast shadows for the other leaves that give us the context to understand what that filled black represents, and you also push the idea that we're filling them in as more of an artistic choice. Always try and reserve your filled areas of solid black for cast shadows only, to avoid this kind of confusion.

• For your aloe vera, just be sure not to cut off the bottom of any form (the flower pot in this case) and leave it open-ended with an edge on either side that just stops. Instead, cap it off with an ellipse - even if this cuts the pot shorter - as this will reinforce the solidity of the form.

Aside from that, very well done! I do need to see that page of branches (and make sure that you've followed the instructions here to the letter - if not, you may want to save some time by doing another page and submitting that).
