For the first 50, your lines are clean overall, with fairly light wobbling present in the set. Your convergences also show good accuracy, though I did see a few lines veer off in the wrong direction, like in box 4, box 24, and box 47.

For the next 50, your lines show improvement, wth fewer instances of wobbling overall. Your convergences also show improvement in accuracy, with fewer errant lines. However, I did see a few lines pair off and converge towards two vanishing points, like in box 53, box 77, and box 98.

For the last 150, very little wobbling is present at the end of the set, demonstrating good technique and consistency. Your convergences also continue to improve, though there are still instances of lines pairing off, like in box 111, box 173, and box 228. While they are less frequent than before, this diagram may be helpful to you. In these boxes, the inner lines (green and orange) 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, I noticed that the back corners didn't have line extensions in The First 50, but it's not an issue since you corrected that from the second set onward.

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.

Hi! Thanks a lot for your time, efforts, and helpful comments. I'm glad to proceed with the lesson 2.

Below this point is mostly ads. Indie projects, and tool/course recommendations from us.
This section is reserved for low-cost advertising space for art related indie projects.
With how saturated the market is, it is tough for such projects to get eyes on their work.
By providing this section, we hope to help with that.

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.

Remember that when you agree with something another user has written, you are putting your own reputation behind it.

Consider the following:

  • If it's homework feedback, does it address each section of the lesson/challenge, or only briefly touch upon one or two exercises?
  • Does it provide clearly defined next steps for the student to follow?
  • Have you read through it thoroughly, or are you simply agreeing so the student earns a superficial badge?
  • Replies you agree with will be visible in your sketchbook

Agreeing blindly just to be nice is a good way to get your permissions associated with this function revoked, so make sure that you genuinely feel that the response is beneficial to the student.
