Looking at your arrows, you're off to a good start. You've captured these with a good deal of confidence behind your lines, helping you to convey the manner in which each of these moves fluidly through the world. That carries over quite nicely into your leaves, where you've not only captured the manner in which they sit statically in 3D space, but also how they move through the space they occupy. You've also got examples here of building up further edge detail (though I would have liked to see this applied to more of these leaves), as well as an example of more complex leaf structure, both of which were done well.

For the attempt at adding texture/detail in the bottom right, remember that as discussed back in Lesson 2's texture section, texture is all about implying the presence of textural forms through intentionally designed cast shadow shapes. Don't get distracted by trying to capture other things, like more general form shading, or by trying to draw filled black shapes that aren't cast shadows. It's important that as you draw any given shadow shape, that you're aware of the specific nature of the form that casts it.

Continuing onto your branches, these are very well done save for one key issue - you're not extending your edge segments fully halfway to the next ellipse, and as such are ending up with really sudden transitions from one segment to the next. As shown here, achieving a healthy overlap between the edge segments is critical to achieve a smoother, more seamless transition from edge to edge.

Moving onto your plant constructions, as a whole I'm very pleased with your results here. You're very mindful of the way in which construction has us forcing specific, tight relationships from phase to phase, and in doing so you're doing a great job of gradually building up complexity in your structures while maintaining the same solidity that comes from the early simplicity we employ. This kind of thing carries through really nicely in how particular you are with each step of the demonstrations, and how in the hibiscus' petals for instance, you drew each flow line right to the perimeter of that starting ellipse, and then each petal right to the end of the flow line. It's little things like this that have a big impact.

There are just a few things I want to call out:

• I noticed you employing cast shadows and line weight in a variety of ways throughout your drawings, and while generally your use of these tools was correct, there were some places where it got a little muddied - this flower for instance. The thing to keep in mind is that line weight and cast shadows are distinct from one another, and they follow different rules. Line weight is kept as subtle as possible (like a whisper to the viewer's subconscious used to clarify how certain forms overlap one another as shown in these two overlapping leaves), and runs along the silhouette of a given form. Cast shadows on the other hand are projected from one form onto a separate surface. It can get as thick/broad as necessary, but it needs a surface to fall upon and cannot simply cling to another form's silhouette. Cast shadows are also subject to a consistent light source - meaning you can't have shadows cast both to the left and to the right of a form. So, to keep it simple, ensure that all your cast shadows are drawn while keeping the casting form and the receiving surface in mind (which generally you do seem to be doing), and for line weight, avoid arbitrarily adding it to reinforce the silhouettes of forms, and try instead to limit its use to where forms overlap, to help clarify the way in which they do so.

• Another point about this drawing - you've left the flower pot open along the bottom edge of the page. This will cause it to flatten into a 2D shape. Instead, cap it off with an ellipse, so it can remain a solid, enclosed structure and maintain the illusion that it is still in fact 3D.

Aside from that, you're doing a great job. I'll go ahead and mark this lesson as complete.
