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 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:

• You have the occasional wobble and quite noticeable arching occurring in your lines. For the wobbling it's likely caused by hesitation when your lines aren't going to be accurate, the arching is a sign that you're not utilizing your shoulder as much as you could be and instead relying on your wrist/elbow.

• 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 so that both ends touch an edge of the face they're 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.

• 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 50 more boxes please. Focus on experimenting with rates of foreshortening, keeping more concrete vanishing points in mind and following the principles of markmaking.

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.
