Drawabox is about a lot of things - and you're right, it's least of all about drawing specifically. Or at least in the sense that "drawing" is about making pretty pictures, which Drawabox couldn't care less about. Even in terms of technical skill, it is about developing spatial awareness, understanding how forms relate to one another in space, etc. But beyond that, you've hit the nail on the head - it's about learning the things you need to be able to learn more effectively. Patience, discipline, an appreciation for the value of failure. We're constantly told in school that failure is bad, that if you don't succeed the first time then it's a mark on your record forever. Drawabox is about learning that failure is not a shameful thing. It is a normal part of the process.

Anyway, let's get started on your critique. Looking at your form intersections, here I'm seeing a lot of good stuff - your linework is confident, your forms are looking solid and believable, and you're doing a pretty great job at establishing how they relate to one another in 3D space, demonstrating a well developing set of spatial reasoning skills. There is definitely a touch of hesitation when you draw those intersections - specifically when they curve - and I can see some cases where you go back over them (often having drawn them smoothly the first time, then wobbling while tracking back over them). Keep an eye on that, and generally consider whether going back over a mark is really necessary. If it is, it's more important that you do so with confidence rather than accuracy, so be sure to use the ghosting method and avoid tracing slowly and carefully.

Moving onto your object constructions, right off the bat I'm very pleased with the fact that you're drawing these with a lot of patience and attention being paid to the level to which you subdivide. With this being the first lesson where we have students jump into this kind of highly planned/precise manner of construction, a lot of them will still hit a wall where after a certain point they feel they've done "enough" and just start eyeballing the rest. I'm very pleased to see that you hit no such wall, and took the subdivision as far as it needed to go, based on the demands of the object itself.

It's also very clear why you were on the verge of burnout - but the discipline and patience you ultimately demonstrated here is fantastic, and will serve you well as you continue to move forwards both through Drawabox (Lesson 7 is a doozy) and in your own studies beyond this.

As far as criticism goes, I don't have too much to call out, and as your construction is coming along great, they're primarily superficial things:

• Remember that as discussed in Lesson 2, we are not worrying about form shading in our drawings for this course. When we fill an area in with black (or in your case, blue), those filled shapes are focused on cast shadows rather than form shading. Form shading doesn't actually add anything that isn't already captured in the construction, but cast shadows can further reinforce the relationships that exist between the forms casting the shadows and the surfaces receiving them.

• This is really more of an extension off the previous point - but to keep yourself from slipping up when it comes to cast shadows vs. form shading, make sure that you're actually designing specific, intentional shapes for your cast shadows, outlining them first before filling them in. Form shading tends to occur based on spaces/shapes that already exist in a drawing - like the whole side plane of a form, or the inner faces of your compass. If you're forced to figure out a new, independent shape along the surface of those forms, then you'll need to think about the form that is meant to cast this shadow, avoiding defaulting to form shading.

To be completely fair, I actually don't have more than that to say - I suggested there were a few things, but even the points I raised were part of the same issue. The rest of your work is spot on. So! I'll go ahead and mark this lesson as complete. Keep up the fantastic work.
