Welcome here! And congrats on finishing this challenge- this is no easy feat. I’ll be looking through it~

Starting with your line quality, this has improved a bunch throughout the set. Though it wasn’t particular wobbly, as a result of, I’m assuming, a stellar lesson 1, it was a little sloppy- particularly noticeable in the hatching lines. I’m guessing that you either thought of these lines as less important (incorrect!), or, in general, didn’t spend as long as you needed to on the ghosting stage. Either way, this is looking a lot better by the end. Your hatching is tight, and consistent (though there may be a little too much of it…), and your confidence in your own line-work quite obvious.

A lot of improvement has been seen in the boxes themselves, too. These started off quite rough- your lines would diverge, you’d extend correction lines in the wrong direction, the far plane would be the one receiving the hatching lines, etc. By the end, save for the occasional back line (which we’ll talk about in a second!), your lines are properly converging, and the boxes themselves mostly correct. One little issue is that the rate of convergence isn’t always consistent (that is to say, one side of it will be dramatic, while another will be shallow), but this is an easy fix. What I’d much rather focus on is the back lines of your box. These are notoriously annoying, as any error present in the outer lines of your box will be reflected by them. One method of dealing with them, that we usually recommend to our students at the end of their challenge, is outlined in this diagram. Notice how we recommend looking at each set of lines (that is to say, a set that shares a vanishing point, not a plane, or a corner) in isolation, paying close attention to the angles these lines form when intersecting over at the vanishing point. If you do, you’ll start noticing certain relationships. The inner lines of the set, for example, have a small angle between them, usually, which becomes negligible by the time they reach the box. So much so, in fact, that it becomes useful to think of these lines as being parallel, thereby giving yourself a free guess, and one less relationship to worry about. Similarly, conclusions can be drawn for the outer lines of the set, too, as their rate of convergence is usually proportional to the size of the angle they form. See if you can make an effort to see these, and make use of these from now on, and this’ll become yet another tool in your tool-set. For now, however, feel free to move on to lesson 2.
