Congratulations for completing the 250 Box Challenge!

From what I can see your line work is well done and your boxes are coming along well. One of the first things I notice about your boxes is their size. If you look back at the instructions here you are only supposed to have 5-6 boxes per page. This is to allow students to draw their boxes at a larger size while still leaving room for you to do your line extensions. Putting too many boxes on your page forces you to draw them at a smaller size. In order to get the most out of this challenge and your warm ups it is better to draw at a larger size. Drawing bigger helps engage your brain's spatial reasoning skills, whereas drawing smaller impedes them.

I also noticed that while you have made some good progress with the quality of your mark making, there is still some hesitation showing, likely from prioritizing your accuracy over creating a smooth, confident looking line. Just remember that the confidence of the stroke is far and away your top priority. Accuracy is something that you will improve on as you continue working through Drawabox and practice ghosting. While it is important that you use the ghosting method of each mark you make while doing Drawabox one thing you can try to help with ending your marks closer to where you want them is lifting the pen off of the page rather than stopping the motion of your arm.

This applies to your extra line weight as well. You have made some good progress applying it so that it blends better with your original mark, but your mark making still suffers from the same hesitation I addressed before. Extra line weight is meant to help reinforce the illusion of solidity in your forms. If you look here you can see that you are meant to apply your extra line weight to the silhouette of your form. Extra line weight should never be used to correct or hide mistakes. Something to keep in mind as well, when you are working through Drawabox you should be employing the ghosting method for every mark you make. This includes the hatching that we sometimes use for our boxes.

I see that throughout many of your boxes, you purposely tried to keep your sets of lines parallel on the 2D page, drawing them all to an "infinite" vanishing point. As explained in this section, because these boxes are oriented with us looking at the corner of the box, we should be drawing it in 3 point perspective - meaning with 3 concrete vanishing points, each set of lines converging towards a real point in space, even if that point is far off and the convergence is gradual.

I think this diagram will help you as well. So, when you are looking at your sets of lines you want to be focusing only on the lines that share a vanishing point. This does not include lines that share a corner or a plane, only lines that converge towards the same vanishing point. Now when you think of those lines, including those that have not been drawn, you can think about the angles from which they leave the vanishing point. Usually the middle lines have a small angle between them, and this angle will become negligible by the time they reach the box. This can serve as a useful hint.

Before moving onto lesson 2, I am going to have you draw an additional 50 boxes. For these boxes I want to see your sets of lines converging towards their shared vanishing point. I will also be looking for less hesitation showing in your mark making. Remember to limit your boxes to 5-6 per page so that you can draw them at a larger size. Boxes 153-156 from your homework are a good example of the size I am looking for. Be sure to reread the instructions along with the links I have left you and take your time. Good luck!
