Welcome to drawabox. It would be helpful if you used imgur to upload your files, and if they weren’t in portrait mode (for reference, this is what I see: https://imgur.com/a/Yh4gpdl), but this is less of a concern for me and more one for the box challenge TA, who’ll need to look at 50+ such images, and zoom into each one. Anyway, let’s take this one exercise at a time.

Starting off, your superimposed lines look good. They’re smooth, properly lined up at the start, and of a consistent trajectory. You’ve not tried any arcing lines, it seems, which is a bit of a shame, but that’s alright. The ghosted lines/planes look equally confident, and quite ambitious, too. It looks like you forgot to plot start/end points for the non-diagonal center lines of your planes, however; be mindful of that. Every line needs start/end points, because every line is drawn using the ghosting method (whose literal first step is ‘plot start/end points’).

The table of ellipses exercise looks mostly good. Your ellipses are a little same-y (with regards to their degrees/angles), and drawn through a little too much – recall that the recommendation is 2-3 times, and ideally, you’d stick to 2 – but they’re smooth and rounded, which is most of it. The ellipses in planes do a good job of maintaining that same level of confidence, despite their more complicated frames; good work! The funnels are more of the same, though I’d have liked to see you be a little more conscious of the degrees of your ellipses, here. Ideally, they’d increase, but even if not, they definitely should not decrease, so be a little more mindful of that. Drawing confidently does not mean drawing carelessly, y’know?

The plotted perspective exercise looks clean, but you should’ve used a ruler for the hatching lines, too. The rough perspective exercise starts off strong, and shows some nice improvement throughout the set. However, where the convergences are on-point, the linework has some issues; namely, automatic reinforcing. Recall that each line is meant to be drawn once, and only once, regardless of how it turns out. In other words, resist the urge to add more ink to a mistake in an effort to ‘fix’ it. Good attempt at the rotated boxes exercise. Despite its issues – that you probably noticed fairly early on – you’ve stuck with it, and seen it through to the end; that’s what we like to see. Overall, your boxes are very well constructed, and they’re snug, and properly rotating. You’ll occasionally forget to draw through one, or mess up their far planes, but that’s not a huge issue, and something we’ll look into in the box challenge, anyway. Speaking of boxes, the organic perspective exercise is well done. It shows a good understanding of how boxes work, and their many overlaps, as well as their size, and foreshortening, make it so that they flow quite well. However, the exercise feels a little rushed, in that you’ve seemingly extending their lines arbitrarily, and met them from the other side, rather than carefully planning them with start/end points, as advised. I’ll assume that you simply forgot, here, rather than intentionally rushed, but do be careful about that sort of thing.
