Hello!

I will do my best to correct your 250 box challenge.

Lines:

• Your lines look stable and with no distinguishable errors in them.

I see that you have applied line weight and shading.

Both well drawn and applied in place.

However, you will want to avoid applying line hatching on the back side of your boxes, as it can confuse the eye.

I like that no line looks rushed drawn.

Box construction:

• It is quite helpful if you have drawn your boxes in various orientations, so you won't be surprised when you are asked to draw them in various positions in later lessons.

• You'll notice that in many of your boxes the lines converge in pairs.

This is a mistake to avoid.

It usually helps to think of the relationship of each line as a set to its vanishing point.

As you will see, the inner pair of lines will have a somewhat similar orientation, while the outer pair will vary more depending on the position of the vanishing point.

If the vanishing point is far away, the lines will be more parallel; and if it is close, the lines will converge faster due to their foreshortening.

• Sometimes the lines of your boxes diverge.

This is a common mistake when drawing shallow foreshortened boxes.

This error decreased as you drew more boxes, so I highlight it slightly.

Conclusion:

Over all; you see a big improvement overall in your latest boxes.

I'll leave you a bit of homework; just complete it when you get the chance, no rush :')
