Starting with your arrows, you're doing a great job of capturing the sense of fluidity in how they move through the world. Back in Lesson 2 however, I did point out an issue where you were not compressing the spacing between the zigzagging sections, and this is still present here. As shown here, foreshortening should result in those gaps getting tighter and tighter the farther we look back.

Moving onto your leaves, I think you've largely done a good job of capturing that sense of fluidity and motion from the arrows, and have used it here to not only capture how the leaves sit in 3D space, but how they move through the space they occupy as well. You've also done a good job of approaching more complex leaf structures as well as more complex edge detail in a way that adheres closely to the structure from the previous phase of construction. I do however want to take this opportunity to jump forward to an issue I actually saw in your plant constructions' leaves which would be worth addressing here.

Looking at this construction, when adding greater complexity to the leaves, you essentially replaced the result of the previous phase of construction, rather than building on top of it. As shown here, you shouldn't be redrawing the portions of the leaf that are already present in the previous phase of construction. I also noticed a really liberal use of rather uneven line weight, and I'm unsure of why it's there. In general, line weight should be subtle (it's a matter of a slight relative increase in thickness from one section to another), and in general it should be used more to clarify the overlap between forms. You've got it getting thicker and thinner all over, in ways that only lead me to believe that you might not have been using the ghosting method when drawing these lines, and perhaps you were trying to cover up some hiccups. Of course I can't be sure of that, but in general keep in mind that you should not be in the habit of attempting to fix or cover up mistakes, as this will only draw more attention to them.

While we're still on the topic of leaves, I can't be sure without looking at the reference, but I suspect that the detail on these leaves would probably have been better off approached using textural techniques as discussed back in lesson 2 - that is, through the use of cast shadows, rather than through outlines as you've done here.

Moving onto the branches, you've mostly done a good job here, although I did notice that there are a number of places where you don't seem to have extended your line segments fully halfway towards the next ellipse. As shown here, that extension, and the overlap between segments that results, are important parts of getting the segments to flow smoothly and seamlessly from one to the next. Despite that, you did in most cases achieve a pretty solid transition, and your branches came out looking solid.

Back to the plant constructions, overall I am pleased with your results. I do however think that this isn't necessarily the best you're capable of, simply by looking at the difference between the components when separated into their various exercises (the branches exercise, the leaves exercise) and how they're executed when you're worrying about the plant construction as a whole. For example, looking at this page, while I think the drawing's fine, I do feel that there are small issues - such as inconsistencies in the branch constructions (although this is definitely at least in part because it is harder to draw these branches when they're narrower), and that some of your leaves' flow lines appear to have been drawn with less focus.

It's actually pretty normal, that when we tackle certain concepts individually, they're easier to focus on, but when we use them as part of a larger drawing, we have so many things going at the same time that it becomes difficult to put our all into each individual mark. It's a matter of training ourselves to focus on the stroke we're drawing, to consider what its purpose is meant to be, and how we can achieve that goal to the best of our ability, ignoring everything else. The ghosting method focuses heavily on this sort of separation, that every step of the process has its own specific responsibilities, and to focus on them only and nothing else. To help with the flow of your leaves, I recommend adding a little 'arrow head' at the end of the flow line, just to remind yourself of how that line is meant to represent motion above all else. While it seems silly, I've seen it have considerable impact on pushing one's focus to where it needs to be, at least in that case.

The only other issue of note I wanted to call out comes down to how you're handling the flower pots and vases. I'm pleased to see that you're constructing them around central minor axis lines, but I do feel that you may be at least in some cases trying to get away with fewer ellipses than are actually needed. For example, the flower pot here needs at least two ellipses to define the thickness of its rim (an outer one, and one inset within it). You also do appear to be struggling somewhat with those larger ellipses - be sure to apply the ghosting method and to draw them from your shoulder to help tighten them up. Of course, practicing the lesson 1 exercises as part of your regular warmups will gradually tighten them up as well.

So, I've called out a number of things for you to keep an eye on. All the same, I'm still pleased with your results, and I'll be marking this lesson as complete.
