Hi Arcayl,

I've counted many times but I can only see 244 boxes so far so it seems like you are missing a page, but I'll made do of what you post for now. Let's begin:

1. Mark-making

Your lines look fairly straight and smooth. The wobbliness does show up from time to time if I zoom in closely. For example, top plane of box 226 - the bottomost line; less visible is top plane of box 223 - the rightmost line. Check out the three levels of ghosting (see this link: https://drawabox.com/lesson/1/14/levels) and the entire page every now and then to make sure you apply the correct technique. Although hatching and line weight is optional, it still offers a lot of practice for making smooth & straight mark. You did around 7 hatching lines for each box on average (it's just an arbitrary number but you get the idea) plus 6 line-weight lines around the silhouette. So in total, that's 3k+ ghosting lines for all 250 boxes in total.

2. Shapes of boxes

I do see a variety of foreshortening rate for your boxes. So nice job! Although I think you should prioritize boxes with shallow convergence (VP is far away from the box & outside of the paper) more than boxes with dramatic convergence (VP is fairly close to the box & inside of the paper) as shallow covergence is what you mostly see in daily life. Also vary the shapes of your boxes more because they all look too similar. I recommend you add more variations where you take one factor of a box to an extreme level, for example: toothpaste boxes (where the length is extremely long but the width is narrow), or pizza boxes (where the height of the box is extremely slim). Each will have different converging issue to deal with so it will add more spice to the challenge.

3.Convergence

The following section has a lot of attached links so take your time to go through each of them:

• Back corners are off from time to time. However, take box 142 for example. If you remove the back corner completely, the overall shape of the box is good. So I think it's not the accumulation of minor mistake you made when measuring other corners that leads up to back corners being off. Rather, I think your back corners look off because you don't know how to position them properly. Although for box 131 - red extending lines, the topmost extending line converges too harsly. But I think cases like this is minor in your submission.

• Here are some notes that I think can be useful for you in future warm-ups. Take your box 150 - red extending lines for example, they have a mistake that is often referred as convergence in pairs (see this image for example: https://imgur.com/KSHwTwo). This is usually a divergence/parallel issue between the edge of the initial Y and the edge of the back corner (see 3rd image of this link: https://imgur.com/a/s4qS8ls - and this link after you go through the previous one: https://imgur.com/a/bYtf93a).

• I recommend you try out my favorite way to plan out all corners for your boxes (see this image for more explanation: https://imgur.com/a/Xg1JDpy). Basically, I'm plotting the back corner before the 3rd corner. In the image, colored lines are ghosting lines and they do not appear on the paper. I only start connecting when I feel 1st, 2nd, 3rd, and back corner are all converge decently to the three vanishing points.

• This is a tricky task because you have to plot 4 corners in the position so that they can maintain this relationship: https://i.imgur.com/8PqQLE0.png in three directions. Therefore, it's important to take your time in this stage and plot as many dots as you need to find a suitable location for your dots (see this image where I throw a bunch of dots on the canvas).

Overall, you did a solid job for the challenge. You tackle the three topics (mark-making, shapes of boxes, convergence) I mentiond above really well. The notes I provided serve as a recommendation to level up your boxes even more. However, I cannot mark your submission as complete yet until you provide the missing page as I said in the beginning.
