Starting with your form intersections, nice work, but with a few things to keep in mind:

• For this exercise, try to stick to drawing one continuous network of intersecting forms per page, rather than breaking it down into groups. This will force you to work through more complex problems, and will keep pushing your spatial reasoning skills forward.

• Don't draw the intersections in a different colour - this builds up the sense in our minds that we're drawing something separate, but in truth those intersection lines are a critical part of construction because they define the relationships between the forms in whatever it is we build up. Doing it with the same colour makes it more concretely "part" of the drawing, rather than separate from it. One way I like to think about intersection lines is like they're the "weld lines" on machined parts - something that physically exist in the world.

Continuing onto your object constructions, you've done quite well throughout the lesson. I can see that you're making good use of the various concepts introduced in the notes for this one, including subdivision and mirroring distances across. I'm also pleased to see that you're really working through these constructions in a step by step manner, generally not making any leaps of spatial logic without really pinning them down in specific terms. For example, you're particularly careful of building up your rounded corners by first establishing them with boxes and sharp corners, and rounding them off towards the end. Very well done.

One relatively minor point I do want to remind you of is that one thing we're not really worrying about doing in these drawings is form shading - that's something I see a little of in your work. It's understandable that there may be some confusion from how in the speaker demo we use some vertical hatching lines, but this is specifically to better convey the rounded corner itself, and is something we use very purposefully (towards a particular goal) and minimally. To put it simply, you gotta have a really good reason to break those basic rules, and I wouldn't say that the much more arbitrary hatching added to your coffee percolator quite meets that standard. Here it seemed to be much more arbitrary, and it was applied to a form that was already fairly clearly rounded. If you do want to use this kind of hatching outside of the course, then the notes here may help.

Definitely avoid trying to capture any local surface colour (like where you shaded in the blades of your pencil sharpener). Treat each construction as though it is covered in the same sort of white surface, as this will help us focus our efforts towards capturing things that occur and exist in 3D space. Similarly, any areas of solid black we do add should be reserved specifically for cast shadow shapes. I did notice in a few places where you'd take a particular face of a form and fill it in (like the internal bits of the pencil sharpener, as well as a couple spots on your stapler). This is actually just more form shading, where we make a particular plane get darker due to its orientation relative to the light source. Instead, cast shadow shapes are themselves entirely separate from faces/spaces/shapes that are already defined in the drawing. These cast shadow shapes, through the design of the shape itself, serve to define the relationship between a form and the surfaces around it, as shown here.

Now, these points I've raised are all really just stylistic - things we either avoid or approaches we use in order to help keep the exercises themselves geared more specifically to engaging our brain's spatial reasoning skills. When it comes to the core constructions here, you're doing very well, and I feel confident that you're well equipped to move on.

I will warn you though - while you're not quite at Lesson 7 yet (the next step is the 25 wheel challenge), Lesson 7 will be vastly more complex than the constructions you've faced here. That doesn't inherently mean that they're harder - in fact, the skills you've demonstrated here suggest to me that you have the capacity already to nail those constructions down. The real challenge of Lesson 7 will be the urge to try and complete them in a similar timeframe to these, despite the fact that they're many times more demanding. So, my advice for that will be to allow each drawing to dictate exactly how long it needs from you. They will definitely be the sort of drawings you'll want to break across multiple sittings, so be sure to let them. Patience really is key.

So! I'll go ahead and mark this lesson as complete. Keep up the good work.
