Hi! No worries in regards to the page sizes- you did good to compensate. Let’s look through these, then~

Starting with your superimposed lines, these are looking good, though I’d have loved to see a few more arcing ones. Nonetheless, what you’ve got here is straight, properly lined up at the start, and of a consistent trajectory- nicely done. The ghosted lines/planes look good, though I notice 2 issues. The first is that they’ll occasionally arc near the end. This is an indication of the student being overly conscious of the end point, and slowing down as they approach it. Maintain a consistent speed, instead. Secondly, I notice that you’ve not plotted start/end points for the non-diagonal center lines of the planes. Be sure to, as that’s the first step in the ghosting technique, which you should be using for every single line that you draw.

The table of ellipses looks great. Your ellipses are smooth, rounded, and of a consistent degree/angle in a frame. You’ve gone through them the correct number of times (though I’d recommend sticking to 2, if you can), and they’re nice and snug. The ellipses in planes exercise starts off a little rough, but improves nicely throughout the set. Your initial ellipses, bumpy/pointy in that first page, are properly circular by the end. The funnels, too, look good, what with the gaps being kept narrow, and the minor axis cutting most ellipses into two equal, symmetrical halves. There’s the occasional misalignment, so I’d recommend spending a little longer on the ghosting stage, not forgetting to rotate your page as necessary, but it’s minimal.

The plotted perspective exercise looks clean- nicely done.

The rough perspective exercise gets worse as you go along, somehow. I’ll assume that it was a new day, and you’d perhaps focused your ghosting on ellipses? Either way, the issues are 2. First, the linework isn’t quite as confident as in the ghosted lines section, though you are essentially doing the same thing. (Don’t think about what the lines are adding up to form- take it one line at a time.) Second, the convergences aren’t quite as accurate as in the first page. I see a few points on your page, but not many, so I’ll remind you that the thing to do here is to check, and re-check each point, to make sure that it’s correct (by ghosting it to its respective end point, and beyond, to the horizon, to see where it intersects it), and then commit to it.

Excluding the corner-most boxes (what happened there?), the rotated boxes exercise looks fantastic. It’s big (huge positive!), the gaps between the boxes are narrow, and they rotate quite comfortably. There’s, as you’ve pointed out, the occasional issue with the back lines not diverging, but this is not only normal, but something that we don’t expect students to overcome until the second half of the box challenge, so don’t let it bother you. The next time you attempt this exercise, simply spend a but longer thinking about how each line should behave, and why.

Save for some occasionally dramatic foreshortening, the organic perspective exercise looks good. You’ve got some nicely-flowing compositions, here, and the number of boxes, and their many overlaps, really help said flow. As does the increase in size, and mostly consistent foreshortening. Nice job, here. As per your question at the end, that’s not something you’re expected to do until the end of the box challenge, if even then. It’s okay to think about it, and experiment, but don’t let it bother you if you can’t quite get it right now.

Anyway, this submission being as solid as it is, I’ll be marking it as complete, and moving you on to the box challenge. Good luck!
