Hello I'll be handling the critique for your 250 Box Challenge.

Your first box challenge seems good enough but you have already drawn those other 50, so I'll just go ahead and review it anyway.

Linework

-Starting by your linework, it looks confident 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 hatching and it is looking tidy rather than rushed, it is good that you are giving each individual line as much time and attention as it requires in order to draw it to the best of your ability, I hope that you will continue to display this patience in the future.

-It seems that you did use lineweight on your first 250 but not on the more recent set of 50 boxes. Either way it is important that you get used to applying it, as it is a useful tool that we will employ on the coming lessons, the most important things to keep in mind is that we should be very subtle when applying it, so only add one extra superimposed line and draw it to the best of your ability.

I also want to quickly redirect you to this diagram which shows the correct way to add lineweight, and you can also see it here in the context of a box.

Box Construction

-You have used the line extension method correctly in order to get more consistent rates of convergence, and all of the sets of lines of your boxes converge which is correct, the only thing that you need to keep an eye out for is lines converging in pairs as shown here. One thing that can help with this is to start thinking about the relationship between each pair of lines and the angles they form respective to their vanishing points, you can see this relationship exemplified here, the inner pair of lines will be always quite similar and the outer pair can vary a lot depending on the orientation of the vanishing point the further away you place it and the closer to parallel the become.

-Lastly I want you to keep experimenting with the rates of foreshortening, sizes and orientation for your boxes. it seems that most of your boxes have a somewhat dramatic foreshortening, so try to draw ones with more shallow rates of foreshortening. In these cases our set of lines will be closer to parallel, but remember that due to perspective our lines will never be completely parallel nor will they diverge.

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 .

Experimenting is a good habit as it helps us to form a better understanding of the concepts we are exploring here, so I hope you will continue to nurture this habit in the future.

Okay I'll go ahead and mark this lesson as complete.
