The issue is that you're not providing a direct link to your homework. In the original submission, you appear to have entered "imgur.com" rather than the specific URL to your hosted work, which usually looks like https://imgur.com/a/ABCDEFG or https://imgur.com/gallery/ABCDEFG.

Even if the post is private, anyone with the actual link can find the submission. Since you did make the submission public though, we can now find your work at https://imgur.com/gallery/oxHTY5Z, but prior to that, we would have been able to access your work at this link: https://imgur.com/a/oxHTY5Z

So in the future, make sure you're sending over the /a/ link, and it won't need to be marked as public.

Edit: Benj should be around shortly to critique your work.

Hi hi, I'm around!

Your superimposed lines are well done. They’re smooth, properly lined up at the start, and of a consistent trajectory. The ghosted lines/planes look solid, too. They’re confident, and you’ve even plotted some start/end points for the non-diagonal center lines of the planes (something not all students remember to do).

The table of ellipses exercise is mostly good. Your ellipses are, for the most part, confident (there are instances where they will start off a little stiff, though, and then stabilize – to fix this I recommend spending a tiny bit longer on the ghosting stage), but they’re not always rounded. Remember that our #1 goal isn’t for these ellipses to be accurate, but rather for them to be confident. Which is to say, a smooth, rounded ellipse that stops short of, or overshoots the frame, is much preferred to a wobbly, bumpy one that doesn’t. The ellipses in planes exercise suffers from this also, but it looks good otherwise. The funnels look better in this respect, likely because you’ve drawn these ellipses faster. The speed you’ve used here is much better for you, I’d say, but still do ghost until ready, and be mindful of our priorities throughout. Also, remember that you’re meant to rotate around your ellipses no more than 3 times.

The plotted perspective exercise looks good. Please refrain from filling things in, however.

The rough perspective exercise doesn’t show too much improvement throughout the set, unfortunately. The linework was solid from the start, so no issues there, but the convergences were not, in the sense that there are none. Rather than ghosting, and relying on your points, it seems like you’ve drawn boxes as you think they should look like (3 sets of 4 parallel lines), but that’s incorrect for this exercise, because we’re working in 1-point perspective; meaning, 1 set needs to converge. I’ll recommend re-reading the material, as well as looking at, and after you feel comfortable, drawing alongside this video, if you can.

The rotated boxes exercise has been cropped in such a way that I can’t tell whether you’ve drawn the reminder boxes, but I’ll assume that you have. The boxes rotate nicely, and are mostly snug. There’s the expected issues in the back (a little flat, not quite as snug), as well as some divergences up front, but this is entirely normal. Your boxes are big, and it’s clear that you’re taking your time with each one, so the only issue really is that of a lack of knowledge regarding their proper construction – something we’ll get into in the box challenge.

Finally, the organic perspective exercise is well done. The boxes look solid (if their foreshortening a little dramatic), and their size and overlaps do a good job of suggesting their flow. Do be careful that your lineweight is not so overt, however. It doesn’t seem like it to our eyes, but a single superimposed line is usually enough to suggest a hierarchy, as it does so to our subconscious.
