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

Linework

-Starting by your linework I can see that you have drawn most of your lines with confidence, and you are using the ghosting method to good effect. However I did notice some cases where your marks got more scratchy and sloppy, I also see a tendency to repeat your lines. It is important to keep in mind that if you make a mistake you should not try to correct it by drawing on top of it as it only makes it stand out more, the proper thing to do is to use the ghosting method to think about each mark's purpose and how you are going to achieve it best, remember that each line is no less important for being part of a larger group, so give each one of them as much time and attention as necessary.

-It is nice to see that you used hatching, though we are getting some mixed results, in some boxes the hatching looks tidy and in others it looks more rushed, coming back to my last point, remember to plan each individual mark and draw it to the best of your ability, the reason we do this is to avoid creating any unintentional focal points.

-I can see that you have used lineweight in some of your boxes which is good as you are getting more practice and it is a useful tool that we will be using in future lessons. However, I do see some boxes where you end up making the lineweight pretty thick, we should avoid this as it takes the solidity of our forms away and turns them into mere graphic shapes, for this reason it is better to use lineweight very subtly, only add on superimposed line and make sure to ghost a good deal so it can overlap better with the previous line. I also want to quickly redirect you to this image which shows how to correctly apply lineweight.

Box Construction

-You have used the line extension method correctly for all of your boxes, and you have effectively used the extensions to get a better feel for how to achieve more consistent and accurate convergences. Just keep an eye out for lives converging in pairs as shown in this diagram, one thing that can help with this is to think about the relationship between each set if lines and the angles they form respective to their vanishing points, this is exemplified in this diagram, you can see that the inner pair of lines is always quite similar and the outer pair can vary a lot depending on the location of the vanishing point, the further away you place the VP the closer to parallel they become.

-I also want you to keep experimenting with the rates of foreshortening, the orientation and sizes of your boxes, I did notice that you stuck to boxes with shallow foreshortening as you started but towards the end you started to push your vanishing points further away. If you have trouble coming up with new orientations for your boxes you can take a look at this image and use it as reference

the important thing is to keep experimenting, this is a good habit as it helps us to better understand the concepts we are exploring in this challenge. I hope you keep displaying and nurturing this habit in the future.

Lastly, remember to pace yourself and if you don't feel like doing the exercises on any given day then don't do them, and.come back to it another day. Anyways, I think you will not need revisions, but just keep working on these things, I'll go ahead and mark this lesson as complete
