Before I start - I know that a lot of people use self-deprecation as a pretty standard ice breaker/form of humour, but when it comes to drawing, it's very easy for people to slip into using it as a defense mechanism. While yours is far from the worst self-deprecation I've seen (calling one's work own work garbage offhand is pretty tame), it still is worth shining a bit of light on as a whole. A lot of people will take that first step of badmouthing the fruit of their labour first, so that when another calls out faults, it doesn't sting so much. One unintentional side effect of that however, is that it also can make critique less effective, because the same door whose opening makes us vulnerable, also gives us an avenue to change, and develop.

So while I know you were just being light hearted, but these kinds of habits can develop without us realizing it, and sometimes just cutting that kind of thing out can have unexpectedly positive impacts on how we view our own work and potential.

Anyway, onto your work! Starting with your arrows, these are looking great. You've drawn them with a great deal of confidence, and they really push through the world with a strong sense of fluidity. This carries over into your leaves, where you're doing a good job of capturing how they not only sit statically in the world, but also how they move through the space they occupy.

One minor thing that I noticed was that you are at times a little loose when it comes to building on top of the existing structure. I can see clear signs in a variety of places where you are definitely building up more complex edge detail one piece at a time, having it flow off the existing structure and return to it (although sometimes it's a bit sloppy and results in a slightly raised edge instead of one that flows right into the existing silhouette, as seen here).

What I'm more concerned about is the general looseness of edge detail like this and this where the relationship between the phases of construction is simply a lot weaker, since each individual spike/protrusion isn't really given enough of a chance to be grounded against the existing structure. In general, keep in mind that construction is about building up one thing through successive stages - but not having every new stage replace what was there previously. We're not redrawing the entirety of the leaf, we're simply adding the parts that change from one step to the next. So, instead of drawing those earlier phases as being fainter, and your later phases as being darker, try to draw them all with the same mark, and allow the pieces from the previous stages that can stand for themselves, do so without being replaced with a new stroke.

Continuing onto your branches, these are largely well done. You're building up simple, solid tube structures, and I'm pleased to see that you're shifting the degree of your ellipses as each branch moves and turns through space. One thing I want you to keep working on though is to ensure that you're extending each segment fully halfway to the next ellipse. You do this some of the time, but you also have plenty of cases where you only extend slightly past the previous ellipse. As explained here, the overlap we get from extending each segment fully halfway to the next ellipse helps to achieve a smoother, more seamless transition from segment to segment.

Finally, looking at your plant constructions, as a whole you're doing a pretty good job here. I'm thrilled to see that you're very fastidious in terms of being sure to draw each leaf or petal in their entirety, even when they're overlapped by others, and you're making good use of cast shadow shapes. I did catch the odd case of you zigzagging edge detail back and forth on your leaves, so be sure to keep an eye on that. Still, as a whole you're demonstrating solid use of constructional principles, and I can see that when you're taking a swing at the use of texture, you're doing quite well in using cast shadows and implicit markmaking.

So, all in all, you're progressing quite well. I'll go ahead and mark this lesson as complete.
