Your submission unfortunately puts me in something of an awkward position, specifically because of the significant number of instructions that you did not follow at various points in the set. You do acknowledge some of these, and I'm glad you do, but it essentially results in a set of homework that is far too mixed up for me to really get any real sense of what you do understand and what you don't - that's essentially why it is so critical for students to take all the time they need to go through the instructions thoroughly, and to use the resources that are made available (like the help of other students on our Discord chat server) in between submissions, especially if you're not certain of what you're doing.

I spent some time thinking about how to tackle this problem, and I think the best solution is as follows:

• I briefly point out all of the kinds of issues I see. This may include issues you already referenced in your submission, as I've found it's a bad idea to rely on students' own assessments as that can lead to blind spots in my critique.

• I will then assign a set of revisions for both exercises that will allow you to create a separate set of work that I can work with. What we have now is simply too mixed up with issues in missed instructions and misunderstandings at different points that I can't be confident I'm assessing your work properly. I will try and keep these revisions limited, but they will have to be enough to properly demonstrate that you understand the material.

So to start, here are the main issues I see in regards to your cylinders around arbitrary minor axes:

• You don't appear to be using the ghosting method when executing your linework (I'm not seeing the usual signs of the planning phase, and while your linework is confidently executed, it seems like you're not applying all of the ghosting method's steps), which is required for all of the lines we freehand throughout this entire course. It's possible this is something you forgot, as your work seems to be spread out over a long period of time. Spreading out your work is not a problem, but it is your responsibility that you account for the fact that you may forget things - whether that means reviewing the lesson material periodically, taking notes and reviewing those, or whatever else it is you need to mitigate the issues that might arise from a slower or more irregular pace.

• I'm also seeing a lot of cases where your lines curve a great deal. Sometimes this just looks like a mistake in execution, but cases like 101 and 102 on this page honestly make it seem like you're doing this intentionally. You might be trying to interpolate between the different orientations of your ellipses - but as this is not done in the instructions, it is not something you should be deciding to do on your own. Another prominent case of this is 130 on this page.

• I also noticed that on occasion you would double up your lines (101 and 102 are examples of this). Fortunately you don't do this very much at all, but I figured I'd call it out as that is not something you should be doing in this course. One line, one mark.

• In this section of reminders from the lesson material, we specifically stress the importance of avoiding having your side edges run parallel to one another on the page (in other words, avoid forcing your vanishing points to infinity arbitrarily, as this isn't something we can just choose to do, it's dependent on the orientation of those edges in 3D space - Lesson 1's boxes section goes into this in more detail). You did this a fair bit earlier on in the set (70 and 71 here are good examples of it, although it did still come up on occasion so I'm unsure if you caught this mistake, or just happened to do it less as time went on.

• Generally you identify the minor axes correctly, but there are cases - like 128 on this page where you seem to go on auto-pilot rather than actually checking. For both of the ellipses on 128, the minor axis would be a 90 degree turn away from where you've got it.

• There are other cases where your cylinders' ends get very circular, and so identifying the true minor axis becomes very difficult - that isn't an issue of its own, but looking at cases like 113 on this page, I suspect you may not be actively thinking about the cylinder you're constructing. When the ellipses' degree gets wide/circular, it's because the ellipse is pointing towards the viewer. If that is the case, that we're looking down the barrel of this form, then in order to have that much space between the two ends, the cylinder would have to be extremely long, which would also result in the far end being smaller - but I don't think this was your intent. This diagram explains this a little further - but basically the perspective there is inconsistent, and not possible.

Continuing onto the cylinders in boxes,

• As mentioned above about the reminders section, the cases like these here where you're drawing your boxes such that all of their sets of edges run parallel on the page (or appear to attempt to - sometimes they end up diverging) is incorrect. As noted here in Lesson 1, "0 point perspective" does not exist. You tend to jump back and forth between areas where you're more likely to just force the vanishing points to infinity (whether some or all of them), and where you're actually thinking about convergences on all three axes, but as the reminder section states, you need to be doing the latter consistently for all of them.

• While it does seem like you started factoring in the minor axis for your ellipses in this exercise, you are doing so in the same manner we do this for the cylinders around arbitrary minor axes. The instructions for the cylinders in boxes have us extending the minor axis lines all the way back so we can very easily compare them at a glance to the boxes' lines with whom they're meant to share a vanishing point.

• Your boxes are coming along okay, although I do get the feeling that you may not have been including your freely rotated boxes with line extensions from the box challenge in your warmup routine (or you may not have been as fastidious about revisiting those other exercises as part of your regular warmup routine, as instructed here in Lesson 0, which would explain a lot), and so you do appear to be unsure of where to spend your time as you construct those boxes. Some months ago, the box challenge material was updated with new videos and demos - I would recommend reviewing them, as well as this video focusing on the Y method from Lesson 1. Pay special attention to the parts talking about "negotiating your corners", so that you know how to spend your time most effectively.

As noted above, I'll be assigning revisions to get a better sense of what you do understand and what you don't, without contamination from where you may not have been as aware of the instructions as you could have been. You'll find them assigned below.
