If you click the link you'll see that it just leads to a page with 3 boxes rather than your entire box challenge submission as you intended.

No worries, glad it was an easy enough problem to solve.

Anyways, hello 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. 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've done well:

• Your lines are looking smoothly, tidily and confidently drawn with very little wobbling occurring.

• When you did include hatching in your previous boxes it was applied with intent rather than being rushed. It helps your boxes overall rather than making them appear messily done which is sometimes the case.

• While not a requirement of the challenge you did try to implement line weight which is great to see. It takes a bit of mileage for most people to become fully comfortable with but it's an incredibly helpful tool so I'm glad to see you start to build up that mileage sooner rather than later

• You experimented with proportions and orientations a fair bit. Experimenting is important as it helps us deepen our understanding of new concepts, I hope you'll continue to build and demonstrate this habit in the future as well.

• In terms of convergences you've become more consistent, there are fewer instances of distorted boxes caused by diverging lines in your later work than when you started which is great.

Things you can work on:

• Something you didn't experiment much with is the rates of foreshortening of your boxes. You kept your vanishing points fairly far away for most of the challenge and tried to keep your lines close to parallel. As mentioned earlier experimentation is important if we want to develop a better understanding of the 3D space we're working in.

• While your convergences have improved there are quite a few cases where you're actually extending your lines in the wrong direction and imagining your vanishing point between the box and the viewer. This means that your lines are actually diverging from where vanishing point should actually be and causing your boxes to become distorted (not as much as they could be since you're keeping your lines close too parallel but distorted nonetheless). Some examples of this in your most recent 50 boxes are boxes (1-3, 7, 8, 15, 40, and 41) as well as some others but those are just the first ones I noticed again while trying to find a few. I put this image together for someone else a while back and while their examples on the left aren't your boxes they suffered from the same issue. On the right you'll see an explanation as well as an example of how you can always tell which way we'll be extending our lines as well as an example box that I quickly threw together. Basically when we start off with a Y we can imagine the central joining point as the corner point closest to our viewer, we extend our 3 lines outwards from this point and continue to extend our sets of lines in these 3 directions.

• You attempt to keep your lines a bit too parallel which results in them diverging. This example 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 just yet as it's important we understand current concepts before trying to add more on top of them, seeing as how each lesson builds on previous content this can lead to unnecessary issues.

I want to make sure you understand how to place vanishing points and extend your lines as well as see you experiment more with rates of foreshortening so I'm going to ask you to draw 15 more boxes. I don't want to give you too many as you've already drawn an additional 50 but it's important that you're comfortable with these ideas.

Once you've completed these 15 boxes you can reply to this critique with a link to them, I'll go over them and address anything that needs to be worked on and move you on to the next lesson once you've shown you're ready.

Remember to follow the 50% rule from lesson 0 to avoid burn out. I know you're capable of doing this and look forward to seeing your work!
