Hey there Reset! From your message, it sounds like you struggled with this challenge, but here's the good news: you finished it and you learned from it. Not only are you beginning to see things in perspective, mentally improving on your sense of 3D, you've honed a sense of perseverance and dedication, even in the face of failure. That's the most important takeaway - you can always improve on your boxes, but embracing this particular aspect of the challenge is very difficult for most people! Nice work!

I can see what you mean about lines going stray, but this improves significantly over the course of the challenge. While you do overshoot your end points in more than a few places, this doesn't concern me because overall, your improvement is clear. You're moving in the right direction. Continue to utilize the ghosting technique in order to hone your accuracy and hit that end point without over or undershooting.

As for your convergences, you show a great deal of improvement here as well. Your boxes at the start show a decent sense of 3D but but towards the end, each set of lines becomes very consistent, with very few stray correction lines. Very nice work on that!

We link these notes at the end of every challenge as a matter of course. They're some extra notes that may help you improve further, or confirm conclusions you came to during the course of the challenge. What they go over is the angle of each line as they approach the box and how keeping an eye on this relationship could improve your convergences. Also, considering each line in relation to the lines with which it shares a vanishing point rather than the lines with which it shares a plane or a corner could do the same.
