Congratulations for completing the 250 Box Challenge!
I can see you made some good improvement with the quality of your mark making. Your lines steadily become straighter and more confident looking as you progressed through the challenge. You drew your boxes at a pretty good size and with a variety of orientations and foreshortening. You also start to do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points!
While your converges do improve overall I think this diagram will help you as well. When you are looking at your sets of lines you want to be focusing only on the lines that share a vanishing point. This does not include lines that share a corner or a plane, only lines that converge towards the same vanishing point. Now when you think of those lines, including those that have not been drawn, you can think about the angles from which they leave the vanishing point. Usually the middle lines have a small angle between them, and this angle will become negligible by the time they reach the box. This can serve as a useful hint.
Congrats again and good luck with lesson 2!
