Congrats on finishing lesson 6, I'll do my best to give you useful advice so that you can improve!

Starting with your Form intersections your work is pretty well done although I think it's better to fill the whole page as I'm seeing a lot of empty space that could be used. As for the intersections themselves they are mostly correct, I've made a few corrections here but overall your spatial awareness is pretty good. I'll just share this diagram which may help clarify some concepts that you still aren't sure about. Also when you submit for lesson 7 I'd like to see bigger intersections as those will really test your ability. Also since you're using digital tools it's especially important that you don't go over a mark once it's been placed down, as it makes it hard to tell where / what you are intersecting. Furthermore I suggest you focus more on boxes during your warmups as some of them are still diverging. Lastly I also want to share this form intersection pack made by Optimus on discord which showcases some examples of form intersections. It can also help to use windows Paint 3D which allows you to make 3d shapes and intersections which can help you see how they intersect.

Moving onto your Object constructions your work here is very well done and holds closely to the core principles of this lesson which is precision. Up until this point, going through Lessons 3-5, we're primarily working in a reactive fashion. We'll put down masses, and where the next masses go depends on how large or small we ended up drawing the previous ones. There's no specific right and wrong, just directions in which we're moving which impact just how closely we matched the reference. You can think of it as a manner of constructing that works from inside out. Conversely, what we're doing here works outside in - everything is determined ahead of time, and as we build out the various aspects of our construction, we either do so correctly based on our intentions, or we miss the mark.

Precision is often conflated with accuracy, but they're actually two different things (at least insofar as I use the terms here). Where accuracy speaks to how close you were to executing the mark you intended to, precision actually has nothing to do with putting the mark down on the page. It's about the steps you take beforehand to declare those intentions.

So for example, if we look at the ghosting method, when going through the planning phase of a straight line, we can place a start/end point down. This increases the precision of our drawing, by declaring what we intend to do. From there the mark may miss those points, or it may nail them, it may overshoot, or whatever else - but prior to any of that, we have declared our intent, explaining our thought process, and in so doing, ensuring that we ourselves are acting on that clearly defined intent, rather than just putting marks down and then figuring things out as we go.

In our constructions here, we build up precision primarily through the use of the subdivisions. These allow us to meaningfully study the proportions of our intended object in two dimensions with an orthographic study, then apply those same proportions to the object in three dimensions.

It's also good to see that you took the orthographic studies/plans introduced in the computer mouse demo and leveraged them far more effectively than was presented there. Orthographic plans allow us to make decisions before constructing the object in 3D. This is best seen in your speaker, sharpener, folding fan and chinese lamp where you have utilized orthographic plans very well. It is also useful to do this for "simple" objects like the ones you didn't include an o.study for, simply because it allows us to make decisions before hand which allows us to focus fully on the construction itself. This is especially important in lesson 7 because the subject matter is so complex, so if all of your lesson 7 constructions are done like your speaker (which is brilliant) then you will learn a lot more.

Finally, be careful of form shading which you've done on the last 4 objects. It's understandable why you included it as the demo's have also done so but they are very old and don't reflect the new material well. Also some of your bounding boxes are diverging so really make sure you practice boxes in your warmups (ideally on paper if possible).

So! As a whole, you are doing extremely well, and are demonstrating the kind of patience and care that will surely serve you well as you finish up the rest of the course. I'll go ahead and mark this lesson as complete. Also don't hesitate to ask any questions if anything is unclear!
