Welcome to drawabox! Let’s take this one exercise at a time, then.

Starting off, your superimposed lines are nicely done. They’re smooth, properly lined up at the start, and of a consistent trajectory. Your ghosted lines/planes look quite solid, also, if a little hesitant near their ends. Likely, you’re slowing down as you’re approaching your end points, in an effort to not overshoot. That’s not necessary, however. What is, is that your lines are smooth, and straight, so keep your speed consistent.

The table of ellipses exercise looks a lot better in its second page, though I’d still recommend taking an extra second or two ghosting each ellipse (and perhaps considering the speed at which you draw them – my instinct is that you’re going a little too fast right now), just to be safe. The ellipses in planes are well done. Do be mindful, however, that you rotate around each ellipse a minimum of 2 times, rather than settling for 1 and change. The funnels are mostly good, too, and what little misalignment issues there are, are fixed, as with the first exercise, by being a little more patient during the planning stage. No worries if they persist, however – mileage will take care of them.

The plotted perspective exercise looks good.

The rough perspective exercise, on the other hand, is a little strange. The start/end points of your lines are a little too big, the lines overshoot a lot more often than they did, you’ll often correct ones that you consider to be incorrect, and so on – did someone else do this exercise?, ahah. At a loss for any answers, what I’ll recommend is that you draw these boxes a little bigger, the next time you warm up with this exercise – the small size (and the difficulty with engaging the shoulder during it), could be the cause of your issues.

The rotated boxes exercise looks great. It’s a little small (for the same reason as before, and because, for this exercise in particular, it gives you some much-needed room to think, we recommend drawing big, here!), but its boxes are snug, and rotate nicely. Their back sides, too – a common sticking point – do the same, so this is looking solid on all accounts.

The organic perspective exercise, too, save for some redone lines (usually, we encourage students to leave mistakes be, but if you insist on fixing them, I’ll recommend a red pen), looks nice. Your boxes flow nice, as per their size and foreshortening, and are solidly constructed, too. Keep up the good work!
