To start, you've doing some excellent work with your form intersections, both with drawing the forms such that they feel consistent and cohesive within the scene in which they exist, but also in establishing the clear relationships between them in three dimensions. There is still room for improvement specifically with how you handle intersections between rounded surfaces and flat surfaces, as shown here, but you're definitely making excellent progress.
Over the course of this lesson, I think you follow the trend most students do. You start out approaching your drawings with a relatively simple breakdown of the structure with some subdivisions to find the location of particular properties, but certain things being established a little more loosely (like certain curving lines not quite being fleshed out in more specific terms as explained here). You then hit a point where construction really requires you to buckle down and define just about every tiniest measurement, and you do not disappoint.
I think when you hit that PS4 controller, you may have come out with your brain a little fried by the end, but the patience, care, conscientiousness and attention to detail that you demonstrated here is phenomenal. You broke every measurement down, did not skimp on minor axes or other constructional features, and the it all paid off. Your construction there was exceptionally well done, and you leveraged subtle but meaningful use of line weight to bring the final object out of the scaffolding very clearly, but without falling into the trap of trying to do a "cleanup pass" and replace y our lines. I'm very pleased with how this came out.
You do continue to demonstrate this kind of fastidiousness throughout your work, although there are some places where a little more could have gone a long way. For example, the bottle on this page was a bit haphazard, specifically in establishing the curvature of its body. It would have been better to establish the cross-sectional ellipses through the midpoint of its height (and maybe even a couple more along that axis) to establish how it occupies space more specifically and directly. Instead, you kind of skipped over that stuff and tried to approximate how it ought to be curved, and it somewhat fell apart on you.
The last three drawings however were once again, very well done. I was especially pleased with the fan, and I feel you did a great job of establishing a sense of weight with its base, and handled the roundedness of the cage really nicely.
All in all, I think you've taken away a great deal from this lesson, and I'm pleased to mark it as complete. Keep up the great work.
Feel free to move onto the 25 wheel challenge. Your freehand ellipses are pretty good, though you still may want to take advantage of the freedom to use an ellipse guide here, as it can help us to stay focused on the core principles of the lesson. If you do, keep in mind that full ellipse guide sets can be pretty expensive, but a "master template" which comes with a number of different degrees limited to smaller sizes can help you get through the last two lessons.
