That’s a good pace~ Hi! and congrats on finishing this challenge! Let’s look through it.

Starting off, your line-work has certainly improved throughout. Though it was fairly confident to begin with, I noticed that the hatching lines were a little sloppy, and the line-weight itself a little inaccurate. Though, even by the end, there’s still the occasional inaccuracy (totally normal, at this stage!), the hatching lines are tight, and consistent. It’s nice to see that this challenge has added to your patience, just as much as to your skills. One tiny thing I’ll point out is that line-weight is applied to the silhouette of the box, not the inner lines. Applying line-weight to the inner lines is far more likely to make your box read as a collection of lines, than hold it together, as intended, so it’s not recommended.

Onto the convergences, I was a little disappointed to see that you hasn’t applied the correction method to your boxes, at least not fully. You’ll generally extend 1 set of lines and call it a day, but there’s 3 of them per box. Not only does this really decrease what you get out of this challenge, identifying (and attempting to correct) your mistakes being where most of the improvement comes from, it makes it really difficult for me, too, because I have to now imagine the correction lines, to be able to judge your convergences, as opposed to just seeing them, and being able to tell at a glance. That said, your boxes look fine. There’s still the occasional diverging outer line, though certainly far less than in the beginning, but this is normal, and likely a result of your super shallow foreshortening. (I’d recommend having it be a little more dramatic, if you can.) As for the inner lines, it becomes useful to think of the angle at which they intersect the vanishing point, as per this diagram. Notice that certain lines, like the inner lines of the set, are close enough together to be thought of as parallel, giving us a guaranteed correct answer, right of the bat. For the outer lines, too, we can draw some conclusions, in regards to how dramatic their convergence needs to be (that is to say, how big the angle) depending on how far they are from the center line. Becoming aware of, and making use of these relationships becomes a really valuable tool in your toolset, to refer to when constructing a box, so try to start seeing them in your own boxes, and I promise they’ll make more and more sense as you do.

For now, however, I’ll be marking this challenge as complete, so feel free to move on to lesson 2.
