Hi there, I'll be handling your box challenge critique.

Congratulations on completing the box challenge, it's definitely a lot more work than most people expect. Not only does it help deepen your understanding of important concepts but it shows your desire to learn as well. Be proud of what you've accomplished and that desire you've shown. That being said I'll try to keep this critique fairly brief so you can get working on the next steps as soon as possible.

Things you did well:

• You're doing a good job of drawing the lines constructing your boxes smoothly and confidently.

• It's nice to see that you're taking the time to plan each of your hatching lines and space them evenly. This helps keep your boxes looking tidy rather than looking like they were rushed on to the page.

• You're doing a great job of experimenting with orientations, proportions and rates of foreshortening. Experimenting is an important habit to build when learning any new skill, it helps form a more well rounded understanding. I hope you'll continue to display and nurture this habit in the future.

Things you can work on:

• Line weight isn't a requirement of the challenge but I do recommend practicing it in your future attempts. It's an incredibly useful tool but one that people often require a fair bit of mileage before they feel comfortable applying it. The sooner you start to build up that mileage the sooner you'll see better results.

• There are times when your lines converge in pairs or you attempt to keep your lines a bit too parallel which results in them diverging. This is an example of lines converging in pairs, and this shows the relation between each line in a set and their respective vanishing point. The inner pair of lines will be quite similar unless the box gets quite long and the outer pair can vary a lot depending on the location of the vanishing point. Move it further away and the lines become closer to parallel while moving it closer increases the rate of foreshortening.

The key things we want to remember from this exercise are that our lines should always converge as a set not in pairs, never diverge from the vanishing point and due to perspective they won't be completely parallel.

To answer your question the simple answer is practice but the more complicated one is that the rear corner lines will nearly always be off and while you should try to make them accurate you shouldn't let them stress you too much. The reason they'll nearly always be off is that they're the last ones we tend to create and they amplify any mistakes we've made up to that point, meaning that if any other line is off they will be as well. Ultimately the goal of the challenge isn't to create perfect boxes (we have tools like rulers and digital tools to help with that), it's to develop our understanding of 3D space which you've done a good job of so far. Just remember to try your best, and remember the tips mentioned above (think of your lines as a set rather than pairs, remember they should always converge at least a bit etc.).

Overall while you did make a few mistakes your boxes are improving so far and with more mileage you'll continue to become more consistent. That being said I'll be marking your submission as complete and move you on to lesson 2.

Keep practicing previous exercises and boxes as warm ups, and good luck.
