Looking over Tofu's original critique, there were a number of issues he called out, and instructions he provided:

• ? Execute your marks more confidently - I think in regards to this, your linework has improved considerably, with marks that are much straighter and smoother, and far less second-guessing yourself or trying to correct mistakes.

• ? Clean up your use of hatching - while you do have some issues getting your hatching lines to stretch across the plane from edge to edge, what you're doing here is far more in line with what we're looking for, so I'll consider that one to be addressed as well.

• ? Draw 5-6 boxes per page as mentioned in the assignment section - You're doing a much better job of drawing larger boxes and limiting yourself to what the instructions suggest.

• ? Extend your lines farther out when applying the line extension analysis - You are indeed extending them further out than before.

• ? Extend your lines in the correct direction, away from the viewer rather than towards them - Unfortunately this appears to be an area where you did not really understand the issue, and so it is still occurring. I'll talk a bit more about this in a moment.

• ? Avoid sets of lines that run parallel to one another on the page, ensure there is always some convergence to each set of parallel edges - This also appears to be an area where you have struggled a fair bit, although it can definitely be influenced by the line extension issue. If you're extending your lines in the wrong direction, then you're not actually getting a clear view of what your mistakes are.

• ? Experiment with both dramatic and shallow rates of foreshortening - This is again related to the last two points, and it may be due to you not extending the lines in the right direction, but across the board it does seem like you're drawing roughly the same box over and over, rather than playing with some boxes converging to vanishing points that are closer (more dramatic foreshortening) and other boxes converging to vanishing points that are much farther away (shallow foreshortening).

And, you definitely seem to have missed this one:

• ? Submit the new work as a new submission, which will cost you 1 additional credit - As your original submission had major issues that would have been avoided by simply going through the material more and following the provided instructions more carefully, you were not assigned normal revisions which would be included in the cost of the original critique. Reason being, a new full critique would be required.

Now, I have manually taken the 1 credit that this submission would have cost you, although I'd prefer not have to do that in the future.

So let's look at the main issues you're still struggling with:

• Extending your lines in the wrong direction.

If you take a look at your last page here, I've marked out a few things in different colours.

In red, I blocked out the face you yourself added hatching lines to - meaning that it was your intention for that face to be one of those facing towards the viewer. Recall that each box is made up of 6 faces, three of which point towards the viewer, 3 of which point away from the viewer.

In green, I've marked out the lines you extended correctly - that is, the ones that you've got extending away from the viewer (based on the red plane facing towards the viewer).

In blue, I've marked out the lines you extended incorrectly, towards the viewer.

If you're not able to figure out which direction to extend your lines, then the analysis we're performing becomes useless. The purpose of the line extensions is to identify where our sets of parallel edges converge consistently - or rather, where they aren't converging consistently, and where this can be improved upon in our next page of boxes.

If however you've got lines extended in arbitrary directions, we do not consistently have the information we need, and thus simply cannot consciously work at improving. Worse still, if you had many lines extending in the wrong direction, you have the potential here of working backwards and regressing, since you'd then be trying to make your lines converge in the wrong direction.

Now, I have one additional suggestion that can help at you at least ensure that you're extending your lines in the correct direction, even if you yourself are not able to identify which direction is "towards" the viewer, and which direction is "away" from the viewer by sight.

As shown here, you can use the original Y you started with to help you find the direction in which to extend your lines. The Y is composed of 3 edges, one from each of the 3 sets, and they all meet at one central point. This central point is the corner of the box that is closest to the viewer, and thus if we extend along each of these arms, starting from that center point and back out along each arm, we will definitely be extending in the correct direction, such that these extensions move away from the viewer.

If you apply the steps in that diagram, you will extend your lines correctly.

• Drawing your edges as being too parallel on the page

This could very well just be the result of the previous issue - without extending them correctly, you may feel like your analysis is telling you to draw your lines more parallel to one another. You also may be confusing some of the things we talk about in Lesson 1 - specifically in regards to those vanishing points "going to infinity", which is how we explain 2 point and 1 point perspective, all in terms of there being 3 vanishing points.

Some students come into the box challenge feeling that if they artificially place all of their vanishing points "at infinity", then they can get away with no convergence at all, simplifying the problem to just one of keeping your lines parallel on the page.

This unfortunately is not true. Reason being, we do not choose to place a vanishing point at infinity. What we choose is how the box itself is oriented in space, how it's rotated and spun around. If and only if the box aligns perfectly to the viewer's angle of sight (in other words, where one set of edges ends up running perpendicular to the direction the viewer is looking), the vanishing point governing those edges

So, if the set of edges you're drawing is meant to run perfectly perpendicular to the viewer, running straight across their filed of view without slanting through the depth of the scene at all, then that set of edges would be drawn as parallel lines on the page which converge towards an infinite vanishing point. Any other set of edges would be drawn as a set of converging lines on the page.

Furthermore, the fact that this box challenge has us rotating our boxes freely and randomly in space basically means that the chances of them aligning so perfectly to the viewer's angle of sight is so small that we may as well not even consider it. Thus, we can force ourselves to always have our lines converge, whether it is very slowly and gradually, or more rapidly and dramatically.

I will say that there are definitely some sets of lines here that are converging, but as a whole it doesn't really look intentional, as there are plenty of other lines that are just staying parallel instead.

Now, I don't want you to have to draw another 250 boxes. It would be well outside the scope of what would be useful, and I can see some efforts being made to applying the points that had been raised before. But we do have to address these issues.

So, I'm going to ask you to draw another 15 boxes, and if you can address all of the points that are still incorrect, we'll consider that good enough. If however there are any cases where those issues persist, we may have to do something more drastic. That's the downside of being given a much smaller set - making a mistake in 1 box out of 100 is easy to overlook. 1 out of 15, however, suggests the potential for a bigger problem.

All you can do at this point is give each box and each mark as much time and attention as you can - and of course, be sure to read through the feedback you've received multiple times. I'm almost hitting 1500 words here, so don't expect to be able to absorb everything in one read-through. You will need to revisit it periodically, and I suggest you read through it at the beginning of each sitting, before working on your revisions.

When your boxes are done, submit them as a reply to Tofu's original critique. Also, keep in mind that we're also looking at which instructions you do and do not follow. An occasional slip-up is no big deal, but if you're consistently neglecting things that have been mentioned, that presents more of a concern.

Man, I only just realized that in my previous feedback I'd tried to be fancy and add checkmarks/x's to show what you had addressed and what you hadn't, but they all showed up as ? instead.... oh well. I hope it wasn't too confusing, and that you were able to pick up on it from the context of the rest of the notes.

Anyway, looking at your boxes, I do think that you've made a clear effort to address the points I raised. You are extending your lines in the correct direction, and while I think this has definitely revealed some areas of weakness (especially in that first page, your convergences were kind of all over the place), 15 isn't really enough to actually achieve marked improvement on this front - though it's worth mentioning that your second and third pages do show that you're actively trying to address the issues, bit by bit.

The only other thing I wanted to call out is that when you go back in to add line weight, you're being way too heavy with the line weight, which is an issue in two ways:

• Firstly, it looks like you're definitely just grabbing a totally different, thicker pen. All of your linework should be done with the same 0.5mm fineliner. The only situation where we're allowed to use a thicker pen, or even a brush pen, is to fill in shadow shapes (something we'll encounter in Lesson 2's texture section) - but even then, those shapes should first be designed/outlined with the same 0.5mm fineliner.

• Secondly, in the notes on line weight for the box challenge I do take some time to talk about the importance of line weight being kept subtle, so I recommend you give that another read.

Now, I am going to have Tofu come in and mark this challenge as complete. You do have a ton of room for improvement and growth, and you will have ample opportunity to work on that as part of your regular warmups (adding this boxes exercise, along with the line extensions, to your pool of warmup exercises as explained here). So there's little sense in holding you back, now that you are showing that you're able to head in the right direction. I would however recommend that you shift your warmups for the next few weeks to put a greater focus on the box challenge exercise, so we can make up for what you may have lost in extending your lines incorrectly beforehand.

Coming in to mark this as complete.
