For the first 50, your lines are clean overall. However, I did see some wobbling throughout the set. Your convergences also show good accuracy, though I did see some lines pair off and converge towards two vanishing points, like in box 3, box 25, and box 46.

For the next 50, your lines show improvement. While some wobbling is still present, most instances are less dramatic. Your convergences also show improvement in accuracy, though there are a few more instances of lines pairing off, like in box 59, box 71, and box 97.

For the last 150, your lines continue to improve, with wobbling further reduced, especially towards the end. However, since it was present throughout the challenge, I do recommend reviewing the information in this section to ensure that you're practicing the proper technique.

Your convergences also continue to improve, though there are still instances of lines pairing off, like in box 107, box 172, and box 222. 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, some of your boxes have some lines extended in the wrong direction, including: boxes 51 and 53, boxes 73 and 74, box 137, and box 207. It's not a major issue since it didn't happen too often. Just be sure to double-check that all lines are extended correctly going forward.

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

Next Steps:

Continue on to Lesson 2, and add rotated boxes with line extensions in the style of the last 150 to your warm-up exercise pool.

This critique marks this lesson as complete.

Thank you for the feedback . I'm going to continue practicing these boxes, as it's a really good practice. I'll try to put some more effort into the issues you've raised here.

A lot of my students use these. The last time I used them was when I was in high school, and at the time I felt that they dried out pretty quickly, though I may have simply been mishandling them. As with all pens, make sure you're capping them when they're not in use, and try not to apply too much pressure. You really only need to be touching the page, not mashing your pen into it.

On the flipside, they tend to be on the cheaper side of things, so if you're just getting started (beginners tend to have poor pressure control), you're probably going to destroy a few pens - going cheaper in that case is not a bad idea.

In terms of line weight, the sizes are pretty weird. 08 corresponds to 0.5mm, which is what I recommend for the drawabox lessons, whereas 05 corresponds to 0.45mm, which is pretty close and can also be used.
