Hey, welcome to drawabox! Let’s take this one exercise at a time~

Starting with your superimposed lines, these look good. They’re smooth, properly lined up at the start, and of a consistent trajectory. There’s the occasional wobble in your arcing lines, so I’ll remind you that 1. our goal is for them to be confident, rather than accurate, so don’t worry too much about the guideline, at this stage, and 2.the smaller a mark, the harder it is to execute from the shoulder, so stick to larger ones, for now. The ghosted lines/plane look confident. I’m pleased to see that you’ve plotted some start/end points for the non-diagonal lines of the planes- most students forget.

Though there’s the occasional stiffness (ghost until comfortable, then execute!), the table of ellipses exercise looks good. Your ellipses are smooth, and rounded, and do a good job of fighting in their respective frames. Here, too, I’d recommend sticking to larger ones, as they’re much easier from the shoulder. Don’t up the difficulty until you’re ready to. The ellipses in planes exercise looks great. Your ellipses maintain their roundness, despite having to touch all 4 sides of the plane. Their rotations don’t have as easy of a time matching up to each other, but this is expected, given the extra goal. Just the same, see if ghosting a little more fixes this. If not, no worries, mileage will. Finally, the funnels exercise looks decent. Your ellipses here are a little pointy, so be especially mindful of your pivot (a pointy ellipse is generally an indication of elbow/wrist.) They’re at times a little misaligned, too, so be sure to ghost them properly, remembering to rotate your page as necessary.

The plotted perspective exercise looks nice- well done. The rough perspective exercise definitely started off a little lacking, but it’s looking nice by the last frame. Still, as there’s the occasional line that’s a little too far off, I’ll recommend spending a little longer planning each convergence. Don’t feel obligated to stick to your original points, and always assume that there’s something wrong with them. Outside of that, the exercise looks nice. Your linework is confident, and you’ve been careful that 2 of the 3 sets of lines are at infinity, as per the rules of 1 point perspective. Great work on the rotated boxes exercise. It’s big (huge positive!), and the boxes are snug. Their rotation is a little slight, and their far planes a little flat, but this is not surprising, and is bound to improve as you become more familiar with boxes in the box challenge. Finally, the organic perspective exercise looks great. There’s some issues in regards to their sizes, occasionally, but their foreshortening is consistently shallow, and they do a good job of following the flow line- as a result, they carry the illusion well. Solid work on this lesson, feel free to move on to the box challenge.
