Starting with your arrows, you're definitely pushing these through with a lot of confidence, which helps a great deal in making the structures feel like they're flowing through three dimensions. This carries over into your leaves, where you're capturing not only how they sit statically in 3D space, but also how they move through the space they occupy.

In the addition of the edge detail however I did notice cases where you were attempting to add multiple bumps at once (before returning back to the existing edge and starting a new stroke), as seen here and here. In general, avoid zigzagging your edge detail back and forth. Construct each bump separately, and if you need to establish some further structure in order to do so, you can break the process up into stages as shown here on another student's work.

Continuing onto your branches, your work here is generally quite well done. I can see that you've taken care to extend most of these halfway to the next ellipse, rather than falling short as many students tend to do. You're also demonstrating some attention to the degree shift in your ellipses as the cylindrical structure moves through space. Well done.

Looking at your plant constructions, overall you've done a pretty good job. I have a few suggestions to offer, but they're fairly minor, and will merely ensure that you continue getting the most out of these exercises.

• When you construct any cylindrical structure - like a flower pot (like the one on this page), be sure to construct it around a central minor axis line. I am quite pleased to see that you did add several ellipses to fully flesh out the structure though. The minor axis line simply would have helped in their alignment. Also, the degree shift between the ellipses is actually backwards here - the ones on the base, which are farther away, should be the wider ones. You can review the Lesson 1 ellipses video for more info on why that is.

• When following along with a demo, be sure to follow it all the way through. With the potato plant here for example, you only went as far as to fill the spaces in between that central foliage in with black, and hadn't yet added any cast shadows anywhere else. As such, that black mass appears to be more of an arbitrary stylistic choice, rather than a shadow being cast upon the dirt below, where the foliage is thickest.

• For that tree stump, you generally handled it well, though I would have treated the roots as though they were branch structures. Also, be sure to draw an entire cylinder for the core of the stump, rather than just the ellipse at the top.

• As we push later into the set, you do have a tendency to draw smaller than you strictly need to. In artificially limiting how much space you give a given drawing, you're limiting your brain's capacity for spatial reasoning, while also making it harder to engage your whole arm while drawing. The best approach to use here is to ensure that the first drawing on a given page is given as much room as it requires. Only when that drawing is done should we assess whether there is enough room for another. If there is, we should certainly add it, and reassess once again. If there isn't, it's perfectly okay to have just one drawing on a given page as long as it is making full use of the space available to it.

• In cases where you have a lot of densely packed petals, like in the sunflower drawing, be sure to draw each petal in its entirety, rather than giving into the temptation of cutting them off where they're overlapped. Drawing them all the way through gives us a clearer understanding of how the petals individually sit in 3D space, and how they relate to one another within it. After all, an object doesn't cease to exist where we cannot see it.

• The leaves on this plant seem to be getting somewhat sloppy, compared to what I know you to be capable of. The center one especially does not maintain tight relationships with the previous stage of construction, causing it to feel flat and overly complex. Make sure that you're giving every construction, every form, every shape, and every mark you draw as much time as it individually requires of you, to be drawn at the best of your current ability.

That about covers it. I'll go ahead and mark this lesson as complete.
