Hey there, TA Meta here to review your box challenge but before we get started, congratulations on making it through. It's definitely a big ask, but looking at your first and last boxes alone, I can see that you got a lot from the challenge. I'm also glad to hear you're figuring out how to enjoy just drawing for fun, that in itself is not always easy for students, especially when they've got other things going on in their heads at the same time.

Your line confidence honestly starts off really strong but by the end, you've got a really nice tapering to your lines that suggests you're learning to control the pressure you're using when you draw lines. I would suggest you get a new pen or try to hold it more vertical (if you aren't already) as this one seems to be on its last legs!

You've made some remarkable improvement in your convergences throughout the set, with your initial boxes showing a lot of divergence - it's clear that your consistent application and use of the check lines has helped you identify and address the issues you were having. That's not to say that you've completely ironed out all the issues in your boxes, they're just much less noticeable, with a lingering tendency to have your parallel lines converge in pairs rather than altogether as in this diagram. This diagram shows the predictable relationship that the angles of the parallel lines of a box have with each other, which may help you iron out those last few inconsistencies.

Finally, I did notice you applied line weight to some of the interior lines of the boxes rather than the silhouette as shown here so make sure that when you practice boxes in your warmups, you also try to practice your line weight on the silhouettes of the boxes. Where you have applied line weight, it's really nice and confident, so keep up the good work there and don't worry too much about the accuracy, since even a subtle bit of weight will still clarify the overlaps in your forms.
