Hi there, I'll be handling your 250 Box Challenge critique.

Overall it seems like you improved a fair bit through the challenge. I think around box 125 is where you started to become more consistent in terms of having your convergences move towards their vanishing points. Your linework is starting to look more solid and will only improve with more mileage as well.

There are still a few cases where your sets of lines converge in pairs rather then all together towards a single vanishing point but it is much less frequently than earlier. (Box 248's red lines are an example.)

You may find this example useful for when you continue to do boxes in your warm ups. (https://imgur.com/8PqQLE0) It shows how you need to keep in mind each line in the set and how the angles behave. Remember that as a vanishing point moves farther away from a box the lines will become more parallel, the 2 lines closest in the set will be the first to experience this, while the outer 2 may have more extreme variation.

You may also want to experiment with line weight in the future as well, while not necessary for this challenge it does help your images stand out on the page once you get a grasp for it and can use it reliably. (https://drawabox.com/lesson/250boxes/1/lineweight)

I think you showed a decent amount of growth through this challenge and deserve to pat yourself on the back, drawing 250 boxes is no easy task. It can be very mentally draining to a lot of people so the fact you have the willpower to get through them all is an accomplishment to be proud of. Great Job and good luck with lesson 2!
