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

Not only does the challenge help deepen your understanding of important concepts but it shows your desire to learn as well. 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, and proportions. 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.

• You're only extending 2 sets of lines rather than all 3 as instructed. This means that you're not gaining as much information when it comes to improving your future boxes as you could be and didn't get as much out of this challenge as you could have.

• At times you're placing your vanishing point between the viewer and your boxes (boxes 233, and 249 are examples of this). This leads to you extending your lines in the wrong direction and your boxes becoming distorted because your lines are actually diverging from where the vanishing point would actually be. Here's a guide I wrote that will hopefully help you place your vanishing points and line extensions more consistently. If you need some more examples you can find them here and a simplified guide below.

• I'd like you to experiment with rates of foreshortening more. Currently you tend to keep your lines close to parallel and push your vanishing points far from your boxes. Try bringing your points in closer so that your lines have to converge more dramatically. Remember that experimentation is important.

• 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.

I won't be moving you on to the next lesson just yet, each lesson builds off concepts in the previous course material so if you move forward with un-addressed issues you end up just creating further issues on top of them.

I'll be asking you to draw 40 more boxes, extend all 3 sets of your lines, try to extend them consistently in the correct direction and experiment with rates of foreshortening. For the first 20 I'd like you to draw all 3 of your vanishing points explicitly on the page after you've drawn your initial Y shape, this will force you to work with vanishing points closer to your box. For the latter 20 you can go back to the original method which should hopefully be easier an easier task after the first 20.

Once you've completed your boxes reply to this critique with a link to them, I'll address anything that needs to be worked on and once you've shown you're ready I'll move you on to the next lesson.

I know you can do this and look forward to seeing your work.
