The first thing that jumped out at me when looking at your work was that your lines themselves suggest a key issue to how you're drawing. The line weight across your lines is really uniform, which generally tells me one of two things (or both together):

• That you're pressing too hard

• You're drawing too slowly

Both of these have similar results, with lines that don't vary in weight, because they have no opportunity to taper on either end. Either you're pressing too hard from the beginning, or you're drawing so slowly that the distance over which the pressure increases is minimal at best. This lack of tapering, and this generally uniform weight results in lines that feel stiff and rigid, with far less life to them than a nice, confident stroke would. That is a critical point you'll need to work on, as it definitely does impede the flow of your lines in a number of places.

Looking at your arrows, you are drawing these with a sense of fluidity to them, but there's a bit of hesitation/stiffness (as mentioned before) that does kind of get in the way. For the most part here the fluidity of the arrows is winning out, but making a point of drawing those lines with more confidence and avoiding pressing too hard will help a great deal. Additionally, when adding those hatching lines, generally try to have them stretch across the ribbon from edge to edge, instead of stopping arbitrarily, simply because it tends to look better.

Now, moving onto your leaves, the rigidity definitely stands out a lot more. You're going through all the steps correctly - you're establishing the flow lines, allowing it to govern how the leaf moves through space, and you're approaching the construction of more complex leaf structures and the addition of greater edge detail really well - you're just not drawing with the kind of confidence that will actually bring those drawings to life.

Continuing onto your branches, I suspect you may have misunderstood how this exercise is meant to be done, as I'm seeing lots of areas where one segments stops, and another segment begins. When following the instructions, you'd be drawing the first segment such that it extends fully halfway to the next ellipse, then the next segment would start at the previous ellipse, overlapping the previous one before shooting off to its next target. As shown here this overlap allows for the segments to flow smoothly and seamlessly together.

Additionally, don't forget to draw through your ellipses, as explained here, and as should be done for each ellipse you draw in this course.

The same pattern as mentioned before - of you following the steps largely correctly, but your drawings feeling stiff - holds true for most of your plant constructions. There is one issue that comes up with some of your leaves, where you skip the step of the simple footprint of your overall leaf shape - instead you on occasion jump into more complex edges too soon, as shown here at the top of this image. The main issue is the confidence of your strokes, however, as described along the bottom.

So, I'm going to assign you some revisions for you to try attacking that problem head on. You'll find them listed below.
