No worries, accidents happen.

This link works, thanks.

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:

• Good work drawing your construction lines confidently, this keeps your lines smooth and prevents wobbling.

• When hatching you're taking the time to space each line evenly which shows that care and thought is being put into each line. This helps your boxes appear solid and tidy rather than rushed.

• You're doing a great job of experimenting with orientations, proportions and rates of foreshortening in your final 150 boxes. 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:

• 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.

While I've noted a few things you can work on in the critique above, you've completed quite the daunting challenge. Overall your boxes are looking solid, it does feel like you don't push all 3 of your vanishing points further from your boxes very frequently (you typically leave 1 close at least) so you may want to practice doing so in your future warmups. That aside you're doing a good job and demonstrating that your understanding of 3D space is improving.

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.
