This is so great! From beginning to the end, your improvement and learning process is palpable. You go from wobbly boxes with diverging correction lines to solid boxes with three consistent sets of converging lines. Your mark-making improved significantly too. Really wonderful work here! I'm definitely seeing that this whole challenge gave you a great deal of mileage and learning, so I do agree that you've learned to stop worrying and love the box lol

As a matter of course, we link these notes at the end of every challenge. While I think you did a great job taming those convergences, these offer a few other techniques that may allow you to hone your accuracy even more. They go over the angle of the line as it approaches the box and how this relationship may help you become more consistent with your convergences. Likewise, considering each line relative to the lines with which it shares a VP rather than the lines with which it shares a plane or a corner may help as well.
