Hey there! Nice work getting through the whole challenge - 250 boxes is quite the gauntlet and you tackled the challenge admirably.

So, first impressions here are that your boxes are looking quite solid from the get go, but your line work is a bit feathery! As you go through the challenge, however, they very clearly improve! Towards the end, you've got some very nice mark-making. While there's still evidence of a wobble, your marks are showing a lot more confidence and smoothness. You'll want to make continued use of the ghosting method in warm up to iron that wobble out, but for now, let's go on to your convergences.

These started out quite strong, but show definite improvement towards the end. The three sets of convergence lines become more and more consistent as you go, with stray lines being few and far between. Really nice work here! You're quickly moving in the right direction. For future practice, I recommend having fewer boxes on each page so you can get a better sense of where the correction lines are going. Right now they're a bit crowded which can hinder learning a little bit.

Overall, though, very good work. We link these notes at the end of every challenge as a matter of course. They go over the angle of the correction lines as they approach the box and how keeping an eye on this relationship may help you tame those stray lines. It could also help to consider the angle of 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.
