First thing learned and the most important is to draw confident lines. Now that i got that out of the way, we need to ask "what's the purpose of 250 box challange?" and that it is to visualise the box in 3D, we learn early on in the "Ploted perspective lesson" what it means if the 4 lines converge to the same point of perspective, and that is: the lines are paralel. Now try to visualise what it mean when they are not converging to the same point. A perfect box is a box that all 3 set of lines converge to the same point, so if they don't it means it's not a perfect box. This is useful when you draw things that you already know the size and their distance of the viewer. Drawing by instinct will come handy after you understand perfectly 3D positioning. i would not say to draw more boxes, i'd say to go back and as an exercise try to visualise the shape of the boxes. I'm also waiting for box review and this is what info i gathered till now. Idk if i have the authority to aprove you to go on but i aprove. Also i think you need 2 aprovals. I'll mark the box challange as complete. (side note: the goal is to visualise an object in space, it's not to draw a perfect box; you draw a perfect box as a result of good visualisation) i think it's safe to move to lesson 2.

hi i'll be the one viewing your work today hopefully i'll be able to provide a helpful but on-point critique.

excuse me for taking one day before starting to write this and so to start off there isn't really a ideal strategy when it comes to tackling this challenge, any strategy that works for you is good enough, and so the main purpose of this exercise is not for being able to perfectly draw lines that would converge in a single point or drawing crisp not overshooting nor undershooting lines, the main purpose of this exercise is for you to gain some mileage when it comes to ghosting as well as improving your spatial reasoning in general and being able to understand how that type of box would be drawn even if the orientation, size, width of the box was change.

another thing to mention is that when you're gonna do the official exercises try to avoid as much as possible: "comments, doodles, notes" since in the future there would be some people who would get distracted from it. if you can't avoid adding those that i mentioned you can just do it on another piece of paper where you can collect your thoughts.

let's start:

• extension lines it's commendable that as you go through the challenge your extension lines is always extended in the right direction, it's also great to see that you drew small little arrows to determine where the lines would get extended and so great work!

• parallel, divergent lines, converging by pairs so far the issue that i've seen is that you're often having some diverging lines and most commonly convergence by pair. https://i.imgur.com/8PqQLE0.png this image here could help you visualize on how we think the lines would converge as a set and not by pairs, as you can see here angles were used to help tell how each individual line would converge as a single set, although you might not get it as first but as you go deeper through this course and keeping this in mind you would understand it bit by bit.

• Experimentation now i've seen that you've experimented with a lot of different orientations, sizes, widths of the boxes that you've done as well as doing both shallow and dramatic foreshortening in your submission, i can see that you've followed the instructions here very clearly and seeing you experiment with what i mentioned would offer great results since you'd learn more by experimenting, overall great work!

• hatching lines, confidence for the hatching lines it's great that it's consistent, tight and has confidence but there are times where it's a bit sloppy, the confidence is there but it isn't consistent or that it isn't touching the side of the plane of the box making it seem like it's floating, this happens sometimes because you might be rushing or that you may have made it way too tight, try not going too overboard with hatching lines and hatching lines are still lines that needs to be ghosted like any other lines.

• lastly is line-weight there are some occasional hiccups wherein you've added line-weight to the inner corners/lines of the box and not the outer-side of the box, there's also sometimes where the line-weight is a bit too thick in one side and too thin in another. when adding line-weight try keeping it consistent and only add atleast 1-2 lines, and it's also mentioned that you should only add lineweight to the outer side of the box so that the silhuoette could be refined and offer a much pleasing result.

overall this is a pretty solid submission, while there's still some room for improvement i'm sure that you're ready for the next lesson. hopefully you'll be able to keep these points in mind and don't forget to do the 50/50 rule as well as doing a 10-15 warmup before each session. good luck on lesson 2, and you can add this challenge to your pool of warmups.
