Starting with your arrows, you've done a great job of drawing these with a great deal of confidence - just remember that as we move farther back from the viewer, those gaps between the zigzagging sections should actually be getting tighter, eventually resulting in the ribbon overlapping itself, as shown here.

Getting back to the confident flow of your arrows, this carries over nicely 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. I did however notice that you made fairly few attempts at adding edge detail, opting instead to stop at step 2 for the majority of these. Step 3 (adding edge detail) was not optional.

As for the cases where you did add edge detail, I noticed cases like those marked here where you ended up zigzagging the edge detail back and forth across the existing edge, which as explained here is to be avoided. Additionally, when attempting the more complex leaf structures (and really as a general rule for constructional drawing), avoid leaving arbitrary gaps between the stages of construction as seen here. You also appear to have neglected to draw the individual flow lines for each of the smaller leaf structures, as shown here.

Continuing onto your branches, you've done a good job of sticking to cylindrical structures of consistent width for the most part, although I can see that you haven't quite approached the edges as explained here in the instructions, where they must follow a specific pattern: each segment starts at one ellipse, continues past the second and stops halfway to the third, with the next segment starting at the second ellipse and repeating the same pattern. You appear to have the segments covering greater distances than that, and when it comes time to stop, you usually do so too early, resulting in a minimized overlap between the segments. This is important, as the overlap allows for a smoother, more seamless transition from segment to segment.

Moving onto your plant constructions, by and large you've done a good job. There's a lot of confidence and fluidity to your marks, and you're generally doing a good job of building up from simple to complex. That said, there are a few things I want to draw your attention to:

• While the confidence of your marks is fantastic, it does tend to lead to an amount of looseness that could be addressed by simply taking more time for the planning and preparation phases of the ghosting method, which precede our confident executions, delivering a greater chance of accuracy without sacrificing the fluidity of the stroke. This helps us to avoid gaps in our forms, as we see here - such gaps can undermine the impression that the viewer is looking at a closed, solid structure.

• Another, similar issue comes about when looking at the relationships between the different phases of construction. Just as what I addressed earlier in regards to avoiding zigzagging your edge detail, we want to do what we can to guarantee tight, specific relationships between the phases of construction. So for example, when drawing flower petals a round an established flow line, those flower petals must only be as long as the flow lines themselves, with their furthest extent falling right where the flow line's tip sits. Cases like this one result in a much looser relationship between those phases of construction, resulting in less of the solidity of the previous stages carrying forward. Always remember - each constructional step is an answer to a question, or a solution to a problem. Once you've answered "how long is this leaf/petal going to be", you should stick to that answer, rather than providing a different one later on and introducing contradictions into the construction. Similarly, when we start our flowers out with an ellipse to define the extent to which each petal will reach, the flow lines we draw afterwards should stop right at the perimeter of this ellipse (you can see such an example in the hibiscus video demo).

• There are some cases where you skip constructional steps entirely - for example, you jumped too soon into the wavy edges of these flower petals. First, you'd draw your basic leaf/petal structures, and then add such wavy edge detail to them, so you're not trying to solve a ton of different spatial problems simultaneously. With the basic structure down, you need only worry about how the wavy edges exist in space relative to the original edge, rather than figuring out all of it together.

While these are things you will definitely need to keep in mind, I feel that overall you're doing a good job. I'll go ahead and mark this lesson as complete.
