Starting with your form intersections, for the most part you're demonstrating a well developing understanding of the relationships between these forms in space. There are a few intersections that are at times a little off, which I've marked out here, but that's pretty normal. In some cases, even when making mistakes, the overall manner in which you're thinking about the problem (like the cone and cylinder) is moving in the right direction, just ends up getting a little reversed.

Continuing onto your object constructions, I'm honestly very pleased with not only your results, but more importantly your process. You mention that you worry about how you were focusing more on projecting orthographics into 3D space, rather than actually constructing - but there's nothing to be concerned about. This course is about developing your internal understanding of how the things you're drawing exist in a three dimensional world, and this is simply a different way of thinking about it.

Throughout the work you've shown immense, and increasing patience and care as you built out each and every construction. You started pretty simply with the demonstrations, gradually getting used to just how far each object's subdivisions could be pushed. With this lesson, we're introduced to this kind of patient scaffolding-building for the first time, and many students will push it to a point, and beyond that arbitrary point, decide that they'd done "enough" and leave the rest to approximation and eyeballing.

You have done no such thing - for each construction, you pushed that subdivision exactly as far as you need to in order to find the precise positioning of every detail and feature. I see no shortcuts, and no cut corners - except for the physical corners you cut in order to lay down adequate support for your curved edges. I'm extremely happy with your results.

The only issues that really arise are the entirely normal ones that come about from us not being perfect machines. Your gameboy advanced got a little wonky, likely due to the subdivisions themselves not being perfectly aligned with the box enclosure. Also, the chess piece definitely suffered from the ellipses, but that's entirely understandable. The reason we encourage the use of ellipse guides is because students at this stage aren't expected to be able to freehand those highly specific ellipses perfectly here.

While full ellipse guide sets that might have helped you in the case of the chess piece are very expensive, and so I don't expect students to get them, "master" ellipse templates are much more affordable. They're a single sheet with a variety of degrees cut out of them, but are more limited in size. I do recommend you try and pick one up when tackling the wheel challenge, as it will help you keep from getting distracted by these more basic elements of construction.

Aside from these entirely normal hiccups, your approach as a whole, and your results - most notably the piece de resistance in your PS4 controller - is stellar. I'm really excited to see what you'll be pulling off when you hit Lesson 7, where this level of finesse and attention to detail will come in very, very handy.

I'll go ahead and mark this lesson as complete, so keep up the great work.
