These pictures are much easier to work with, thanks.

In the future if you could number your challenge subject (in this case boxes) or at least the pages it would also be appreciated, I'm assuming these pictures are in order but having it labeled helps paint a better picture of where you started and where you ended up. It also allows us to point to specific forms easier.

Not only does the challenge 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:

• Your lines are smooth and confidently drawn.

• When hatching you keep your lines fairly evenly spaced which shows that you're putting some thought into their placement rather than rushing.

• It's good to see that you're experimenting with proportions, orientations and rates of foreshortening. Experimenting is an important part of the learning process, it helps us form a more well rounded understanding of the concepts we're tackling. It's a great habit to build and one that I hope you continue to nurture in the future.

Things you can work on:

• There are times where you're imagining your vanishing point between the box and the viewer and extending your lines in the opposite direction. This leads to your lines diverging away from where the actual vanishing point would be and causing your boxes to become distorted. The left box on your first page's blue lines would extend downwards instead of upwards, and the two boxes on the left of your last page also suffer from this issue as well. Here's a guide I wrote up that will hopefully help you know how to place vanishing points and line extensions consistently.

• 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 15 more boxes, number them and focus on placing your vanishing points in the correct spot and having your lines extend 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.
