For the first 50, your lines are very clean overall, though arcing and wobbling is present throughout the set. Your convergences also show good accuracy, though I did see some lines pair off and converge towards two vanishing points, like box 9's orange lines, box 23's blue lines, and box 49's orange lines.

For the next 50, your lines show improvement, with less wobbling overall, though some arcing is still present throughout the set. Your convergences also show improvement, though I did see a few more instances of lines pairing off, like box 60's orange lines, box 77's green lines, and box 100's blue lines.

For the last 150, your lines continue to improve. Arcing is still present, but most instances are less dramatic than before, especially towards the end. However, since it was present throughout the challenge, I recommend reviewing the information in this section and ensure that you are practicing the proper technique.

Your convergences also continue to improve, though there are still instances of lines pairing off, like box 114's red lines, box 172's green lines, and box 231's green lines. In these boxes, the inner lines (green and orange in this diagram) diverge instead of converging at the vanishing point. Keeping in mind the angles of neighboring lines can help when planning the box's construction.

As an aside, box 24 and box 34 are missing some line extensions. It's not a major issue since it didn't happen often, but I want to point it out for future reference.

All said, you did well. I'm going to mark this challenge as complete.
