All things considered, despite your uncertainty and general discomfort with the assignments, you've drawn these with a fair bit of confidence, and have mostly done a good job. Now, there are a number of things I'll point out, but the bulk of the concerns are small - missed instructions, certain tendencies that stand out, and so on. I think there are choices you can make as you move forwards that will help improve your overall results, but all in all you're doing a pretty good job.

Starting with your form intersections, I think your forms here have been drawn in a way that feel quite confident and solid on an individual basis. When it comes to the intersections however, you're still struggling quite a bit. I think that one of the contributing factors to this is that you decided that your main priority was going to be including as many forms as possible (which is certainly admirable), and as such ended up drawing the forms relatively small on the page. This impeded your capacity for spatial reasoning, which resulted in a lot of mistakes when it comes to determining how the forms would intersect. Given that intersections are inherently one of the most challenging things we tackle throughout all of Drawabox, and that the actual intersections we encounter within this exercise are far more complicated than anything we'd deal with when actually drawing objects, this handicap ended up costing you a fair bit.

Here I've pointed out a number of intersections that weren't correct. I didn't point out all of them, just focused on identifying a few different kinds of mistakes. Above all else, it is important to keep in mind just what an intersection is - it is a line that runs along the surface of both forms simultaneously. This means that if we were to pick at any individual point along this intersection line, we'd be able to ask ourselves, "on the surface of which form(s) does this point sit?" When done incorrectly, you'll find points that sit along the surface of one form, but in order for that to be true, it would have to sit either inside of or outside of the other, rather than on its surface. When done correctly, all points will in fact sit on the surface of both forms, at the same time.

Even now, the difficulties you're experiencing are not abnormal, nor shocking - but I do think that choosing to draw the forms much smaller did make navigating these spatial relationships more difficult for you. In the future, I recommend you draw them maybe 1.5x as large, focusing less on drawing as many forms as you can and more on putting down the forms one at a time, and thinking about their specific relationships with the forms that have already been placed.

Moving onto your object constructions, this theme of drawing larger applies here as well, for the same reason. All things considered you did a pretty good job (despite the handicap), but there's definitely a theme of quantity being the most important thing, and a number of your drawings ended up crammed into a small corner. Often times when students tend to draw a lot of smaller objects, they feel compelled to also draw more quickly - perhaps with the focus of doing at least one full page in a sitting. When we make the decision to complete at least a full page, we inherently split up the time of that session into the number of drawings we'll need to fill the page. This means that the drawings themselves are no longer receiving as much time as they need to be drawn to the best of your current ability, and instead are somewhat more rushed in the interest of the arbitrary goal of a full page.

This can result in mistakes like these, where you've got your enclosing boxes those parallel lines diverge as they move farther away, instead of converging, and further phases of construction where the lines end up slanting unintentionally, resulting in them turning lopsided. The mark I made about your barrel's curvature doesn't actually fall under this umbrella of sloppy mistakes - it's actually one I see from students on occasion, and is just something I wanted to point out.

Later on, you start to get much bolder with your brush pen/heavier markers, which is nice and all, but don't forget this point from the section where I encourage the use of a few different tools:

Ballpoint pen for your linework (don't switch pens to do any sort of "clean-up" pass - use the same pen through all your lines, including construction/box subdivision/etc)

You ended up getting pretty carried away in using your thicker pen to strengthen and replace the outlines of your drawing. This is something I discourage because it creates a much starker separation, dividing your drawing into "underdrawing" and "cleanup pass". Even in the context of simply adding basic line weight, having as significant a jump as we see here tends to make things appear more graphic and flattens them out.

While what's going on with this page (in terms of the use of heavy blacks and such) does look kind of nice, it goes against a number of things that were raised in Lesson 2's texture section. These points were recently rewritten in order to draw greater attention to these points - specifically the difference between form shading and cast shadows, and avoiding any use of generic hatching lines when attempting to convey texture or shading. I strongly recommend that you go through that section again, along with the newly recorded videos.

So! I've mentioned a lot of different points for you to keep in mind, but all in all your work is still demonstrating a well developing grasp of space, form and construction. You're very thorough in your subdivisions and the steps you take to ensure that your constructions are laid out correctly (especially later in the lesson - a lot of the sloppy issues I brought up were biased towards the beginning). So, I am confident in marking this lesson as complete.
