Starting with your arrows, these are flowing really confidently and fluidly - just don't be afraid to let those zigzagging sections overlap one another as they get far enough away. You generally do a decent job of capturing that sense of fluidity in your leaves as well, although there is a touch of hesitation and stiffness in how you draw them, when compared to the arrows. It's not always present - some of these flow quite well, so you're rather close, but make sure that when you draw that initial flow line you always do so with a sense of movement and force behind it. Think about how you're drawing this line in 3D space, and how it represents how your leaf moves through the space it occupies.

You do a pretty good job with most of your experiments involving greater edge detail and more complex leaf constructions, although this leaf in particular definitely went awry. Specifically, you drew the various arms of the leaves, and then instead of just simply bridging the gaps from arm to arm as shown here, you tried to envelop the whole thing. Be sure to read through that example a little more closely so you better understand how to approach it. Whenever you're bridging caps like this, it's the sort of thing you want to keep as minimal as possible, going across the smallest gap.

Continuing onto your branches, you're doing a pretty good job with this exercise. There is certainly room for improvement, and that'll largely come with practice - though there are one thing I can suggest as you continue working on these. Drawing the marks with a little more confidence, and getting into the habit of lifting your pen off the page as you hit the end point (instead of slowing to a stop) will result in a bit more of a taper at the end of the stroke which will help it blend more seamlessly into the next segment.

Moving onto your plant constructions, you've largely done a good job over the entire set. There are a couple things I want to point out, but by and large you're demonstrating a good grasp of how to construct the relevant forms and how to combine them to create more complex objects while maintaining their believability, and the illusion that they exist in 3D space.

As a whole I'm actually totally pleased with your constructions - you're not skipping any significant steps, and you're very conscientious about drawing through each and every form you add, so as to better grasp how they all exist together within the same space.

When you get into texture, however, is where I think I need to clarify precisely what you should be aiming to achieve when it comes to that phase of a drawing. Everything we do is for the purposes of communicating something to the viewer. With construction, we convey to the viewer what they need to know to understand how they might go about manipulating this object in their hands. With texture, we convey what it'd be like to run their fingers over its surfaces. Right now I suspect that you might be a bit more focused on texture as being a form of decoration for the drawing, for the purposes of making the drawing itself impressive and complex, but that is not really what we're after here.

When it comes to communication, we can often get away with much less, and often times the whole "less is more" adage applies. That isn't to say you approached it incorrectly, it's just that with every mark we draw to add detail, we take risks. We take risks in whether that mark properly follows the contour of the form, we take risks in terms of creating potentially unintentional focal areas that will draw the eye to somewhere we don't mean to. As a whole, when adding texture it is always best to give it a light touch, to focus on what it is you wish to communicate, and to add only enough to achieve that goal.

That said, your approach to texture - in terms of the use of cast shadow shapes and all - have all been leveraged quite well, and the particular focus on cast shadows in the ornithogalum really helped it pop. This is one of those where I'd say there was a lighter touch of texture compared to some of the previous ones, and it had the greatest and most meaningful impact.

So! All in all, I think your work is coming along very well, though you've got a couple things to keep in mind as you move forwards. I'll go ahead and mark this lesson as complete.
