Hi MrEpie, I'll be handling the critique for your 250 box challenge. So there isn't a deadline for any of the lessons you can take as much as you want.

And about the spacing, you should definitely have sticked to 5-6 boxes per page, drawing small makes it harder to draw some marks and to ghost your lines too, and it also doesn't leave you too much room to experiment with the orientation.

But now let's address your overall work

-Starting with your linework it is coming along very nicely and you have drawn smooth and confident lines for most of the challenge.

• Keep in mind that when addig lineweight we need to ghost through our superimposed lines and should only add one, as we want to keep it as subtle as we can

• We also need to ghost trough our hatching lines, as they are running on a flat surface they have to be as smooth and straight as possible.

-You have kept your vanishing points relatively close for most of the challenge, you want to experiment as much as you can with the foreshortening of the boxes, a box with its vanishing points too close hints that we are looking at a very large object, and the subjects that we'll draw in later lessons being not that big demand that you also get comfortable with drawing with very shallow foreshortening. An unexpected upside of this is that you never tried to draw any parallel set of lines which is a common mistake to see, and also you didn't draw many diverging sets of lines.

-I'd like you to experiment with the boxes orientation a think that can help you is this image.

-Keep an eye for lines converging in pairs as shown here, that's a mistake that you made from time to time.

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.
