Jumping right in with your form intersections, your linework here is definitely improved over your submission in Lesson 6, although I am noticing that you still don't appear to be applying the ghosting method as directly as you should be - for example, the absence of start/end points on the straight lines suggests that you're not skipping elements of the planning phase, and there is some wavering to the strokes that suggests that you might be executing a little more hesitantly than you could. Always remember - the ghosting method is about how we allocate our time into three distinct phases, each one with its own priorities. By investing our time in the planning and preparation phases, we're able to take the responsibility of considering the nature of the mark we wish to make away from the execution phase so it doesn't actually require any additional thought, allowing us to focus only on a confident execution. So - you've improved on this front since the last time I looked at this exercise, but there are still signs that you can be more mindful and intentional with the application of the ghosting method.

When it comes to the intersections, your work is definitely coming along better. The only notable issue I noticed is when you allow the intersection line to curve more rapidly when wrapping around a rounded surface than that surface would really allow, as shown here.

Lastly, don't forget to define the minor axis for your cylinders, so you have something to help define the desired alignment for the ellipses on either end, and when you do build a structure around a minor axis, don't place the ellipse centered around the end of the minor axis line. Have the ellipse sit entirely over the line so you can clearly gauge how the ellipse is bisected by it.

Continuing onto your cylinders in boxes, unfortunately it seems that you didn't apply the line extensions in their entirety - you extended the boxes' edges, but did not identify the contact point lines, nor did you extend your minor axis lines back so as to be able to compare them to your boxes' vanishing points. You also skipped one set of lines on the box towards the top-middle, and in general your boxes tend to avoid convergence in the manner explained to be a mistake here in the cylinder challenge notes.

I'm starting to get the impression that while you're generally quite capable, you're not reviewing the instructions for previous exercises and concepts nearly as much as you should be, and that is causing you to make some considerably sloppy mistakes.

Moving onto your form intersection vehicles, these are well done, although are actually taken well beyond what the exercise actually asked. This is from the homework section, where they were assigned:

These are purely constructional, approach them as you might the form intersections from lesson 2, by drawing primitives (boxes, cylinders, etc). Focus on drawing through your major geometric forms. you can break them down as far as you like, but remember that we're not interested in the smaller details - just on laying down the primitive forms in the arrangement of a vehicle. Do not use grids, subdivision, etc. Just simple primitive forms as you'd draw them for the form intersections exercise, focusing on each individual primitive form, one at a time.

Weirdly enough however, while you ended up taking these much farther than you needed to, your more detailed vehicle constructions were kind of the opposite. In fact, a lot of the more meticulous construction you applied in the form intersection vehicles was what was expected from the later vehicle constructions (just with a few more stages built up on it), but when you got into the more detailed ones, you seemed to reallocate how your time was being spent rather than simply putting in more time. This resulted in what was essentially you laying down the basic grid, and then working from a lot of estimation/eyeballing when drawing the actual vehicle. While you've certainly demonstrated a fairly strong, well developed understanding of 3D space in doing this (especially with constructions like this space ship and this jeep, the point of every lesson throughout this course is not for the student to demonstrate what they can do, but rather to demonstrate that they understand how to perform the exercise so they can continue doing so on their own, in order to further refine and develop their skills.

I do understand the confusion, to a point - being that the course is in something of a mixed up state with many demonstrations that are many years old, and that the course itself is in a constant state of evolution, so while the text may push for certain things, the demos don't always reflect that. We are working hard to address this, but it's a long process of overhauling the video/demo material, and one in which we make little progress as most of our time is spent on critiquing homework submissions. So, for now the best we can provide are sections like this and this section from Lesson 6 to which it refers, on the topic of the use of orthographic plans. Additionally, this section on handling curves, which specifically states not to jump straight into them but rather to build them up first as a chain of straight edges or flat surfaces, rounding them out only after they've been fully established, is also relevant.

Now, I am fairly confident in your ability to perform this exercise in this manner, but before I mark this lesson as complete I am going to assign some limited revisions to ensure that you are applying the concepts correctly. You will find those revisions assigned below.
