Alrighty! So overall you're doing a pretty good job, but there are a few things I want to draw your attention to.
Starting with the arrows, these are spot on. You're capturing them with confidence and fluidity, and really establishing how they move through space. This carries over pretty nicely into your leaves as well, where you're capturing not only how they sit in space, but also how they move through the space they occupy. That said, while I am pleased you also jumped into more complex leaf structures, it appears that you didn't play around with building up any more complex edge detail, as shown on step 3 of these instructions.
It seems that his isn't something you delved much into in your plant constructions either - there's the hibiscus demo on this page which did get into it a little, and you applied it well enough, but I definitely would have wanted to see more of it. It really gets into the principles of construction and how we lay down structures to build upon them later, creating a complex sum of many successive phases, with each new step building onto the same structure rather than outright replacing it.
Your branches are looking pretty well done, just make sure that you're extending your segments fully halfway to the next ellipse, as explained here. All things considered you're already achieving a virtually seamless transition, so this isn't a big deal, but generally speaking that full extension does help to achieve smoother and more seamless shifts from one segment to the next. Aside from that though, you're doing a great job of maintaining the illusion of solid structures.
One other thing you may want to consider is having the degree of the ellipses shift as you slide along the length of the branch structure. Remember that the degree of the ellipse depends on the position and orientation of the given circular slice. This is explained, with physical props, in the most recent iteration of the ellipses video from lesson 1.
Moving onto your plant constructions, for the most part you're doing really well, I just have a few small things to suggest:
When it comes to using line weight, avoid using it quite as liberally as you did on the top-left flower from this page. Don't use it to reinforce the entire silhouette of all your forms - focus it in limited, localized areas to clarify specific overlaps. Also, avoid tracing back over your lines carefully and hesitantly, as this focuses too much on how those lines run across the flat page, rather than on how they represent edges moving through 3D space. Draw them confidently, using the ghosting method. This will be easier, since we're only adding them to fairly limited sections and blending them back into the existing linework.
When constructing flower pots, like the one for the cactus on this page, always build them (and any other cylindrical structure) around a central minor axis line. While this may be because you were struggling with drawing those ellipses, but it does look like you were trying to make the upper ellipses wider and the lower ones narrower. The relationship should actually be reversed, with the ellipses getting wider as they move farther away from the viewer (as discussed in regards to your branches).
I'm glad to see that you've been enthusiastic about drawing lots of plants on each page, but your first priority should definitely be to give each drawing as much room as it requires on the page. This will help you engage your brain's spatial reasoning skills as well as make it easier for you to use your whole arm while drawing. Drawing artificially small, in a sort of cramped manner, will actually make those things more difficult, resulting in more overall clumsiness.
Aside from that, you're doing quite well. I'm really pleased with the way you built up some of the more complex structures, with layered petals being built around cylinders. This shows you're understanding a lot of the core constructional concepts.
I'll go ahead and mark this lesson as complete.
Feel free to move onto lesson 4.
