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:

• Your construction lines are looking smooth and confidently drawn.

• Line weight isn't a requirement of the challenge so it's nice to see you're applying it anyways. Most people need to build up some mileage before they feel comfortable applying it so I always recommend starting early. The sooner you feel comfortable the sooner you see better results.

• You're doing a good job of experimenting with orientations. 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:

• You tend to draw fairly small, I'd like you to draw larger in the future. Drawing large will help you become more comfortable working from the shoulder and allow you to see any misakes you've made more clearly.

• Your hatching lines could be tidier. Just like any other line we want to take our time planning them using the ghosting method, space them evenly and draw them confidently.

• At times you're placing your vanishing point between the viewer and your boxes (every box on the page with boxes 234 to 247 have at least one set as some examples). 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. There are also some additions to the 250 box challenge page that you may find helpful, like this less in-depth method of checking your boxes as well.

• I'd like you to experiment with proportions and rates of foreshortening more. Outside of a small handful of boxes most of them are fairly similar in terms of proportions, mix in some longer/wider/thinner boxes more frequently to build up experience and get a better grasp of how your lines will react. When it comes to foreshortening you tend to keep your vanishing points far from your boxes and your lines as parallel as you can. Bring your vanishing points in closer to see how your lines behave when they have to converge more dramatically. Remember that experimentation is important and will help build up a well rounded skill set.

• 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'd like you to draw 30 more boxes please. Tidy up your hatching and draw larger, limiting yourself to 5 or 6 large boxes per page. Focus on experimenting with proportions and rates of foreshortening as well as trying to get your lines to converge consistently in the correct direction.

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.
