To be completely honest with you, I don't really have that much to offer here. I'll do what I can, but the demos aside, as you get into the meat of drawing your own everyday objects, you demonstrate an incredible degree of patience, care, attention to all the subtle little characteristics and details of your objects, and a willingness to go as far and as hard as it takes to get the drawing done.

Starting with your form intersections, you're clearly demonstrating an excellent grasp of how these forms relate to one another in 3D space. I see a couple places where I suspect you might get a little confused as to the orientation of your forms - like the cylinder up in the top right of this page seems a little like both its faces are pointed towards the viewer, based on how it's interacting with the forms around it, but all in all you're showing an excellent execution of a variety of complex relationships. Throughout, you're also executing your linework with considerable patience and care, and are applying line weight quite effectively.

Some of your demos - specifically the barrel and the computer mouse - don't come out that great, but they definitely do show an adherence to the decisions you make throughout the constructional process. You choose your proportions, then you stick to them - you don't go back and try to fix things when they start going awry, and that adherence to the marks and choices already put down on the page helps you ultimately end up with something that still feels pretty solid by the end of it. So while it's clear that the barrel ended up being too long and too narrow (definitely missed out on the sense of having that barrel swell outwards), and the computer mouse ended up being too short (it looks like the outer box was short, and then you also ended up leaving a bit of space in front of the mouse), the results still felt pretty sturdy and real.

I do have one small thing to mention about the computer mouse that isn't really all that important - just a point about how you filled in an area along its side with hatching. Always remember that the filled areas of black (which is basically what you attempted there, with the limitations of ballpoint), should be reserved only for cast shadow shapes, not for actually colouring in surfaces. Remember that since we're not working with colour, we need to treat the entirely of our drawings as though they're of a flat, even colour. There are a few, somewhat inconsistent exceptions to this - for example, the vertical lines packed in along the inner faces of your clip are okay, because they help show the reflectiveness of the metallic surface (which is arguably more of a texture.. type.. thing.) Anyway, point being - don't fill in things in an attempt to capture local colour.

Now, arguably there's something to be said about maybe working with a brush pen to fill in those solid blacks, though depending on the brush pen this might actually not look super great alongside the ballpoint. It is understandably difficult to fill in areas to be solid black with ballpoint, as we see in your spray bottle where it ends up looking kind of sloppy (despite the excellent construction throughout) - it's almost the quality of the construction that raises the bar, and the lesser attempt at filling those shadow shapes in that end up with a somewhat anticlimactic result. In your later drawings you appear to pick up on this, and work less with shadow shapes, or focus them in to be a bit tighter (so they're easy to fill in more densely).

While I am really pleased with your construction throughout, not all of them came out well. The PS4 controller for example ended up feeling lopsided, with the far end coming out way too narrow. I think this is because you estimated the more boxy blockout of the left side handle being much narrower than you should have, as shown here. It's undoubtedly difficult to estimate it working off that, so I would instead have started with a much blockier, more easily understood structure, and then smoothed it out in successive constructional phases. Regardless, these kinds of controllers are definitely really tough, and might be an interesting challenge to give yourself after you've completed the whole course. In a lot of ways they're really similar to cars, which as you well know are the big boss of lesson 7.

I'm honestly blown away with your skull drawing. The way in which you were able to project your orthographics to create such a solid, believable, complex structure is incredible, let alone the fact that it was amidst this forest of constructional lines that no doubt would have been a huge struggle to work with at every turn. It's crazy that you didn't get confused, even the slightest miscalculation or misinterpretation of a line could have had significant repercussions for the result. But you really, really nailed it.

That is ultimately the drawing that colours this whole submission for me - the mistakes you may have made throughout are nothing compared to the sheer victory you have with this skull. You've clearly taken the spirit of the lesson to heart, even if you demonstrated it best with a subject that probably doesn't fit the bill of an "everyday object". Had you messed up, I would have smacked your hand for having chosen something well out of scope - but since you succeeded, I'll just say well done.

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