You definitely start off this batch a lot weaker than you finish, in that with some of the early leaf drawings you're not at all following the instructions. This does show that you're improving, and that you are learning, but that you might have a predisposition to barreling ahead rather than thinking about what exactly is being asked of you ahead of time.

Starting with your arrows, just a minor point - keep exaggerating how the spacing between the zigzagging sections compress in space as we look farther back. While the amount of zigzagging here doesn't necessarily allow me to judge whether or not you understand how perspective applies to it, there are signs that you're generally hesitant to let that space get tighter, or ever allow those zigzagging sections to overlap one another. In the upper right there, it actually widens as it gets farther away, which is not in line with reality. When drawing these, focus on how perspective applies to both positive and negative space.

The leaf on the top of this page, as well as the maple leaf there, categorically go against the exercise. The leaf on the far left-middle of the page is closer in that you're actually following the steps of construction, though your additional edge detail there treats the simpler shape of the leaf laid down in the previous stage as a loose suggestion, instead of as solid scaffolding. Observe carefully how in this demonstration the one with the checkmark touches that earlier shape directly, coming off of it and then returning to it. It respects this as a structure onto which it is being built, not a sketch on a page meant to be ignored or adjusted as needed.

Your branches exercise is moving in the right direction, although I can see that you're definitely rushing through it. The marks don't show a whole lot of preparation preceding the actual execution of the mark, but even moreso the hatching you've placed along the ends is visibly sloppy. This is present in a lot of your constructional drawings, where you're putting the lines down quickly and somewhat thoughtlessly, and treating it more like a loose sketch.

This drawing however, is visibly better. Are there issues? Yes - for example, you're not drawing through each form in its entirety, instead allowing the lines to stop where a given form is overlapped by another (drawing through forms is important to better understand how they exist in relation to one another). You're also still drawing lines reflexively - I can see several places where you've drawn an additional mark automatically, instead of purposefully executing just a single mark. And there certainly is rushing, but when we compare it to what you did for this same plant in your last attempt, you're demonstrating a LOT more patience and care.

At the end of the day though, while you're showing some moves forward, you're still looking at drawing as though it's just sketching. Like you should be able to produce good work by instinct and intuition, rather than through explicit planning and thought. If you compare what I do in the daisy demo to what you're doing, the processes - not just the quality of the resulting lines - are fundamentally different. It's assumed that you'll have difficulty drawing your lines with as much precision, but it seems to me that because you don't feel confident in your ability to draw in this manner, you try and change the process itself to something you may be more comfortable with. You're replacing the problem, instead of allowing yourself to do it badly.
