Starting with your form intersections, the forms and intersections themselves are very well done, but it is worth noting that your pages are pretty far from filled. There's plenty of space that could have accommodated several more forms, allowing you to get more from the exercise as a whole. Always think of your exercises in terms of what you're getting out of them, rather than the idea that the assignments are an imposition on your time, and therefore something to "get out of the way".

Continuing onto your object constructions, overall you've done quite well. You're showing a good deal of patience and care in applying the various subdivisions that are required. It's not uncommon for students at this stage to still be getting used to the kind of precision we can achieve by simply taking the time to subdivide appropriately, and for those students to take certain leaps of intuition (resulting in a decrease in precision), you've put a lot of work into pinning almost everything down to a tee.

With some of your initial bounding boxes, like this one for the stand mixer, I did notice that the initial form was a bit off. As you can see with the line extensions I drew, all three sets of lines were very slightly diverging as we move farther back from the viewer. In this case in particular, it was particularly rough primarily because it seems you tried to avoid any foreshortening all together, opting instead for an axonometric/isometric representation. This unfortunately isn't an option - perspective projection itself requires that there be at least some convergence in your lines as they move away from the viewer, except in the very limited situation where the set of lines are running perpendicular to your angle of sight. That's not the case in most circumstances, and definitely isn't here, but it is a shortcut some students try to take to avoid having to think about perspective, and unfortunately it doesn't work as they'd hope.

Now there were some cases where the proportions were a bit of an issue, such as the monitor/tv, but that's honestly pretty standard for this lesson. It isn't until Lesson 7 that we start actually looking at ways in which we can construct things to scale (as it's remarkably annoying and complicated to do so) - but for the purposes of this lesson, we are far more interested in the solidity of the resulting construction and not whether it matches the reference image perfectly.

To that point, I'm honestly really pleased with your rubix cube, and I think it was an excellent challenge to tackle. It certainly lends itself to the whole subdivision thing, but constructing these independent boxes together, set with completely different vanishing points, is great thing to take a swing at. Now, arguably you should have taken it a bit further and applied rounded corners to each of the different pieces, rather than leaving it to just the structural elements - I think this might fall back in line with what motivated you to leave the form intersection pages before they were filled - but all things considered, you still did a great job.

The last point I wanted to call out, has to do with your barrel. I'm pretty pleased with the fact that you employed an ellipse to determine the open position of that door, but I did want to mention that the ellipse itself appears to have been drawn and positioned somewhat arbitrarily. You did put down a minor axis based on the hinges, which is correct, but you'd want the ellipse itself to represent a circle that sits on the same ground plane as the barrel itself, rather than floating loosely in the air.

Here's something a little closer to correct.

Anyway, all in all I'm still pleased with your work. Just a quick reminder - when you get into lesson 7, you will want to get used to putting a lot more time into each individual drawing, and pushing just how far you're willing to break your constructions down. Many students have those drawings take several hours each.

With that, I'll go ahead and mark this lesson as complete.

Woops! I must have hit the wrong button. This should mark it as complete, and it should backdate it to when you submitted the lesson originally, so you should be good to submit your wheel challenge.
