Hello I'll be handling the critique for your 250 box challenge

Linework

-Starting by your linework, most of your lines are drawn confidently while maintaining good accuracy, which means that you are using the ghosting method to good effect. I also like to see that you are using lineweight, and you are applying it correctly. There are only a few instances where you add more than one superimposed line. Keep in mind that if we end up making the lineweight too thick we will end up taking the solidity of our forms away and turn them into mere graphic shapes. Only add one superimposed line and do your best to overlap them completely, if you make a mistake leave it like that and do not try to correct it. This diagram shows how to correctly apply lineweight and you can also see it here in the context of a box.

I also like to see that you are using hatching and it is looking tidy rather than rushed which means that you are taking your time with each individual line, so I hope you keep displaying this patience in the future

Box Construction

-You have used the line extension method correctly and all of your sets of lines converge which is correct l, due to perspective our sets of lines will never diverge nor be completely parallel. The only thing you should keep and eye on is line converging in pairs as shown here, one thing that can help with this is to start thinking about the relationship between each set of lines and the angles they form respective to their vanishing point , this relationship is shown here you can see that the inner pair of lines will be always quite similar and the outer pair can vary a lot depending on the location of the vanishing point, the further away you place it and the closer to parallel they will become.

-Lastly I want you to keep experimenting with all kinds of rates of foreshortening, orientation and angles for your boxes. I can see that you stick mostly to boxes with dramatic rates of foreshortening, instead try to experiment with more shallower rates, in these cases the sets of lines will be closer to parallel. If you have trouble coming up with new orientations for your boxes you can take a look at this diagram which you can use as reference.

We get the most out of these challenges by experimenting a lot, as it helps us to form a better and more grounded understanding of the concepts we are exploring here, so don't forget to keep nurturing this habit in your future assignments

Okayy, that should be about everything I wanted to address, I'll go ahead and mark this lesson as complete
