Hello, and welcome to drawabox. Congrats on completing lesson 1; I’ll take a look at it for you.

Starting off, your superimposed lines look good. They’re smooth, all lined up at the start, and of a consistent trajectory. Particularly nice work with your arcing lines. The ghosted lines/planes look solid – though there is the rare course-correction near their ends. Remember to maintain a consistent speed throughout, rather than slowing down at the end, in an effort to stop at the correct spot; more so than accuracy, it’s confidence that we’re after.

The table of ellipses exercise looks great. Your ellipses are smooth, though not always rounded. The issue is, particularly, with the thinner ones – I’m worried that you might be reverting back to a lesser pivot when handing those sharp turns; be sure to check back, from time to time, to confirm. Also, remember that ellipses in a frame need to maintain the same degree/angle as their neighbors. The ellipses in planes exercise look fantastic. Your ellipses are smooth, and round, despite the increase in difficulty – keep this up. The funnels, too, are nicely done. Consider increasing the degrees of their ellipses more gradually, however.

The plotted perspective exercise shows a great deal of patience – well done.

The rough perspective exercise is a little mixed. The convergences look fantastic; great job there. The linework, however, is a little lacking. Regarding the quality itself, give this section another read. Also recall that each line is drawn once, and only once, regardless of how it turns out.

The rotated boxes exercise looks quite clean – nice job with the lineweight, and hatching. The exercise itself looks solid, too, what with the boxes rotating, and making use of their neighbors’ edges. Save for the occasional convergence issue, which we’ll address in the box challenge, I don’t have much in the way of criticism here; solid work.

Finally, the organic perspective exercise looks good. Your boxes are mostly correct, and, as a result of their increase in size, and consistent, shallow foreshortening, they do a good job of conveying an illusion of flow, too.
