Starting with your arrows, you're doing a pretty solid job in keeping the arrows flowing smoothly and confidently through space. You're also doing well to explore how the spacing between the zigzagging sections compresses as we look farther back, though I'd encourage you to push this even further, as shown here.

That smooth fluidity carries over nicely into the leaves, where you've done a great job of capturing how they not only sit in 3D space, but also how they move through the space they occupy. You're also doing a pretty good job in adding more complex edge detail to your leaves with a strong, specific relationship to the previous phase of construction (rather than zigzagging back and forth across it). That said, I do want to make it clear that you should not be treating each phase of construction as an opportunity to redraw the entire edge. As shown here in a critique of another student's work, we should be focusing only on drawing the part that changes from one phase to the next.

The next thing you'll want to explore with your leaves is constructing more complex leaf structures, like the one shown in this demo.

Moving onto your branches, you are mostly doing these quite well, but I am seeing instances here and there where you're a bit loose and haphazard in following the instructions of the exercise. As shown here, the previous segment should extend fully halfway to the next ellipse, and the next segment should start at the previous ellipse. This is meant to create a healthy overlap between them, allowing us to transition more smoothly and seamlessly from one to then ext. Furthermore, making a point of overlapping the previous segment and using it as a runway (even when it went off its intended trajectory) will help limit cases where the edges diverge, creating those little tails. We can see in your pitcher plant drawing how being more sloppy/haphazard with the relationships between the segments resulted in more visible hitches in the flow of the overall edge.

Moving onto your plant constructions, these are largely quite well done. I have just a few minor issues to point out:

  • When constructing your leaves and petals, don't leave an arbitrary space between the end of the flow line and the end of the petal. The flow line answers the question of how the leaf/petal flows through space, and how long it will be. Constructional drawing is all about breaking things down into individual steps where we can assert these kinds of 'answers' one at a time, but it is important that we then adhere to them throughout the rest of the construction, even if they end up deviating from our reference image. Otherwise we introduce contradicting answers in our construction, which undermine the viewer's suspension of disbelief.

  • In most of your drawings your linework has been much more purposeful, but I Did notice that in this hibiscus the outer silhouettes of each petal ended up being very scratchy. I'm unsure if you just ended up doing this in a more chicken-scratchy fashion from the beginning, or if it happened when adding line weight. Either way, always remember that every mark - be it initial construction or the addition of line weight - should be drawn using the ghosting method, maintaining proper flow and consistency. Linework like this suggests a lack of planning/preparation.

  • When constructing cylindrical forms like flower pots, construct them around a central minor axis line to help align your ellipses. Additionally, remember that as we slide away from the viewer along such a cylindrical form, the degree of a contour ellipse will get wider. Lastly, be sure to define the opening of the flower pot with both an outer and an inner ellipse to create the impression of a thickness to its rim, rather than leaving it feeling paper-thin.

All in all, your work is coming along well, just be sure to keep these points in mind. Above all else, don't let yourself be tempted to draw marks quickly and without thought - when you draw purposefully and with intent, your results come out vastly stronger. If the difference between your better and weaker results is just time and patience, then there is no reason not to be knocking each one out of the park. I'll go ahead and mark this lesson as complete, so keep that in mind as you move on.
