Hello, and congratulations on completing this challenge! I’ll be looking through it. Now, things definitely started off a little rough, your lines not even connecting in the right places, or extending all the way, but, I’m happy to say, they’re looking a lot better by the end. There’s still a few issues, however, so let’s tackle them one at a time.

Starting with line-work, this has improved considerably through the set, though it’s still not quite there. Even by the end, your lines, and this is particularly obvious in your hatching, look a little wobbly. Remember that confidence is our #1 priority here, not accuracy. Also, be careful that line-weight is applied to the silhouette of the box only.

Likewise, the convergences improve by a lot, as well. The outer lines properly converge, instead of diverge, and the only remaining issue is in the (notoriously annoying!) back lines. To help, take a look at this diagram. If you study it carefully, you’ll notice that certain relationships can be observed between the angles lines in a set form when intersecting over at the vanishing point, and the lines themselves. The middle lines of a set, for instance, have a small angle between them, which becomes negligible by the time it reaches the box. This is important, because, knowing this, we can think of them as parallel, thus giving ourselves a guaranteed correct answer. Conclusions can be drawn in regards to the outer lines, as well, whose degree of convergence is proportional to the size of their angle (usually much larger in comparison!) It’s not something you develop an understanding of overnight, certainly, but it’ll come, provided your do your due-diligence, and try to see it in your boxes. Be sure to continue working on them, as you progress through this course, and they’ll get even better- I promise. For now, however, feel free to move on to lesson 2!
