Starting with your arrows, you've got them flowing quite nicely through 3D space. One thing I want you to keep an eye on however is how you compress the spacing between the zigzagging sections as they move away from the viewer. In the top left of the first page, you did an arguably decent job of this, though the arrow directly to the right of it, you tend to keep the gaps more consistent, which doesn't do as good a job of conveying the depth in the scene. You jump between these two approaches, which suggests to me that you do understand how foreshortening should apply to your arrows, but that you need to think more about it to apply it more consistently.

Moving onto your organic forms with contour lines, you've done a pretty good job of sticking to fairly simple sausage forms as mentioned in the instructions. One thing I am noticing however is that you're not fully drawing through your ellipses as you should be. Sometimes you'll draw through them once before lifting your pen, sometimes 1.5 times, sometimes a little more than that, but you need to be pushing yourself to draw through them two full times before lifting your pen each time.

As a whole, you're demonstrating really good control over your contour curves - they're drawn with confidence and fitting snugly between the edges of the forms. Your ellipses aren't quite as well controlled in this regard, so make sure you're applying the ghosting method there to give you the best opportunity to draw them with greater precision, without sacrificing the nice confidence of your strokes you've got currently.

One last thing - right now you're drawing the degree of your contour lines to be quite consistent over the course of their lengths. The degree of a contour line basically represents the orientation of that cross-section in space, relative to the viewer, and as we slide along the sausage form, the cross section is either going to open up (allowing us to see more of it) or turn away from the viewer (allowing us to see less), as shown here.

Your work on the texture analyses is coming along well. You've got a great focus on shadow shapes, and you're doing an excellent job of controlling their density as you shift from left to right. You're also showing a pretty well developing set of observational skills throughout. You continue to hold to these quite well throughout your dissections, though there are some textures where you tend to fall back into outlining your textural forms a little more than you should - specifically ones like the dry mud, the bricks, etc. where there are more concrete, separated textural forms present. These notes should help you think through these problems.

Jumping ahead to your form intersections, great work - you're doing a great job of drawing these forms such that they feel cohesive and consistent within the same space, and also have a great start on the intersections. That's not to say your work is perfect - the intersections are expected to be extremely difficult, and you're approaching them with the kind of boldness and confidence I like to see. We don't expect students to have prior experience or any real success with them - we mainly want to see them trying them out, so they can start thinking about how forms can relate to one another in 3D space and how those relationships can be defined on the page. You've done this very nicely, and I can see the gears already turning in your head. We will continue exploring this concept throughout the rest of the course, and I expect you'll continue to develop on this front at a rapid pace.

Lastly, your organic intersections are similarly coming along well (specifically the first page), capturing how the forms interact with one another as three dimensional forms rather than as a series of flat shapes stacked on a page. You're also doing a good job of creating an illusion of gravity in how they slump and sag over one another.

Admittedly the first page is a lot better than the second - in the second you don't appear to be thinking as much of these forms as being set up in a physical pile. Always try and think of them as a pile of filled waterballoons - you're not piling them on the page itself, but on an imaginary floor, trying to figure out how they'd all be arranged in a semblance of stability.

All in all your work is coming along well. I'll go ahead and mark this lesson as complete.
