Hi! Welcome to drawabox, and congrats on completing this lesson! Let’s look through it. (And, by the way, that brand of pen is just fine!)

Starting off, your superimposed lines look solid, save for a slight tendency to arc. To fix that, it’s recommended to arc consciously in the opposite direction. Other than that, and the fact that you’ve not, at least intentionally, tried out any arcing lines, things look good – your lines are smooth, properly lined up at the start, and for the most part of a consistent trajectory. The ghosted lines/planes look quite good, too, though here, as well, there’s some course correction near the end. Try not to be so conscious of the end point, if you can. Rather than stopping at the correct place, it’s far more important for the resulting line to be smooth, and straight.

The table of ellipses exercise looks good, save for a few minor issues, which we’ll address one at a time. First, your ellipses have a tendency of starting off a little stiff, for which I’ll recommend spending a little longer on the ghosting section. The execution one needs some mindfulness, too, because you need to be aware of how many times you’re rotating around your ellipses. A minimum of 2 times (2 full times, not 1 and change), and no more than 3, is the recommendation – try to stick to it. Finally, see if you can lift your pen off the page at the end of the rotations, rather than flicking it off, to get rid of those little tails at the end. The ellipses in planes look great. They maintain their prior smoothness, and do a good job of fitting into their respective frames, too. The funnels look fairly solid, too, and the minor issues of spacing, and alignment, are easily fixed by increasing your ghosting time, and remembering to rotate your page as necessary during it.

The plotted perspective exercise is nicely done.

The rough perspective exercise shows some nice improvement over the set. Your lines make a visible effort to converge, in the second page, and it’s clear from the many unused points on the page that you’re taking your time planning them, too – some more would certainly be better, as the convergences are still not perfect, but no pressure. What I will point out as needing improvement, however, is the line quality. It’s not quite as good as in the previous sections, though, seeing how the process of drawing a line hasn’t changed, there’s no reason for this.

The rotated boxes exercise looks very good. It’s big (something we encourage, as the bigger you draw, the more room your brain has to think), and seen through to the end. The boxes themselves are as expected, and do a good job of respecting their neighbors. The rotation isn’t quite there, sure, but it rarely is at this stage, so no worries. Maybe revisit this exercise as you progress through the box challenge.

Finally, save for the automatic reinforcing (remember that each line is drawn once, and only once, regardless of how it turns out), the organic perspective exercise looks good, too. I’m especially pleased to see that you’ve drawn through all of your boxes. Their increase in size, and consistent, shallow foreshortening do a good job of communicating the illusion of flow, too – well done, all around.
