Welcome to drawabox, and a big congrats on completing Lesson 1. Let’s take a look at it, shall we?

Starting off, your superimposed lines are looking mostly good, though I will request that you be a little more mindful of their trajectory – it needs to be consistent. Your ghosted lines/planes look solid – smooth and straight – their only issue being that their start/end points are a little big. Remember that the idea is that a perfect line should swallow them both.

Moving on to the ellipse section, the table of ellipses exercise looks alright. My initial instinct is that you’re drawing a little too quickly, and also not ghosting enough, so do consider re-considering that, but for now, I’ll mention that your ellipses aren’t always drawn through a full 2 times (remember that the 2 is a minimum), and that you’ll sometimes flick your pen off the page at the end of those rotations. See if you can lift it off, instead. Save for these same issues, the ellipses in planes are well done. The funnels are, unfortunately, entirely misaligned. Ghosting is the key, here, but also consider how you hold your arm. For me, I find I produce the best results when my arm is perpendicular to the minor axis – see what works for you.

The plotted perspective exercise has some issues with its lines – they’re not all perpendicular to the horizon. I’m used to seeing this with the final line, the backline, since errors accumulate and reflect themselves there, but there’s no excuse to not have the other ones be perpendicular – it’s an exercise drawn with a ruler, after all.

The rough perspective exercise looks better in what I’m going to assume is the first page (the pages are neither numbered, nor in order), but you’ve still not kept your back lines parallel/perpendicular to the horizon, as instructed. Remember that them heading to the vanishing point is not your only goal. You also need to juggle them being parallel/perpendicular to the horizon. If they’re not – in other words, if their vanishing points are not at infinity, then this is not 1-point perspective.

The rotated boxes exercise is entirely unfinished. If you take a look at the example homework, you’ll notice that your boxes haven’t been drawn through – in other words, you can’t see all 12 of their lines in their entirety. Instead, you’ve simply drawn their front faces, and extended the back lines for as much as they’d be visible under normal circumstances, and called it a day. For one, these aren’t normal circumstances – we draw as if we have x-ray vision. Beyond that, we’d normally be able to see some of their back sides. Finally, your linework here is scratchy, and the hatching lines have been drawn with your wrist, it seems.

The organic perspective exercise has a lot of automatic reinforcing (meaning, you going over the same line multiple times). This is not something we like to see in general, but it’s especially bad here because a thick line tends to draw our attention, but the box in question could be further in the back – thus, what its size and foreshortening is saying (that it’s far away) is being contradicted by what its lineweight is saying (that it’s close).
