Hi there LILYWANNADRAW, i'll be the one looking over your submission and hopefully i'll be able to provide a helpful but on-point critique,

So to start off as you progress, your markmaking and the confidence in your lines have improved, you've also experimented with a good deal of shallow and dramatic foreshortened boxes as well as varying orientations. There are still some issues here but congrats on being able to complete this challenge, not everyone in this curriculum have the patience to draw 250 boxes for half a month or even longer, so hopefully after this challenge you'll be able to continue pushing through this course.

• Extension Lines - The most common issue that i've found throughout the challenge is that you seem to struggle to find the correct positioning of your extension lines, now the problem with incorrect positioning of the extension lines is that it could make distorted boxes look natural and when you're correcting boxes, it isn't quite accurate and you might not be able to tell if what you're doing is correct or not, one solution to this mistake is to draw small little arrows in the initial y like the one shown here.

• Hatching & Lineweight - Greatwork in your hatching as well as your lineweight, i can see for the line-weight that you were able to only add 1 additional line creating a appealing silhouette for the box, there are some hiccups like adding some lineweight to the initial y or at the back plane of the box, but it's very minimal. for the hatchings you've also done good for making them consistent and tight.

• Convergence by pairs, divergent lines, parallel lines - so far the common issue that i've seen here is the convergence by pairs and parallel lines, this is a common issue among students and so keep in mind that a set of line should converge into a single point not onto multiple points, a line should never diverge away from the vanishing point, and due to perspective a line should never be completely parallel. so this image here https://imgur.com/8PqQLE0 could help you visualize or atleast open another pov when it comes to converging extension lines.

• in some pages there are boxes that you've drawn that's a bit too small, when drawing boxes it's better to only limit each page with 5-6 boxes and make them big so that you won't be able to give any room for your wrist.

Overall this is a pretty solid submission, i won't be letting you go for a bit since i'd like to see you do 15 boxes without the extension line extending in the wrong direction, but generally i think you've done a great job and have grasped the content of what the lesson is for.

i think you are doing it fine i see some improvements when you hit 200 boxes

well i see your boxes look clean and i like it and so far when you hit around 200ish boxes you start understanding where the vanishing point are located i think you are good to go to lesson 2
