When doing step 2, I try to think of the direction of the line (its own perspective), to start the line, and the imaginary receding lines of the other perspective points and where they intersect, to stop the line that I'm drawing. Step 2 https://imgur.com/GgJPRo, Step 3 https://imgur.com/mRCP0u2, Step 4 https://imgur.com/hVy2BxQ. It's tricky, and I'm still struggling, but I have a sense that the box will be fairly good or fairly bad if the step 2 was way off the imaginary intercepting point of the receding lines.

When drawing a box in a 3 point perspective, when you draw the first 3 lines that will recede each to its own perspective point, make sure the have more than 90 degrees between them https://imgur.com/GLxiR8s.

The fourth line and up that you will draw, each of those lines needs to take into account all 3 perspective points, first its own so you know where it should go, then the perspective point of the other two in order to know where to stop https://imgur.com/GgJPRo1. That is tricky, and since you should draw everything without using a ruler and without drawing each receding line, it's a matter of doing the boxes "trying" to think in this way for each line https://imgur.com/mRCP0u2, https://imgur.com/hVy2BxQ, -then- when you have finished the page and are drawing the receding lines to check for mistakes, for each line ask yourself; what was wrong? Its own point perspective? Or did it stopped before or after the point in which the other perspective lines recede?

Next time you draw remember what mistakes you made and try to draw the same boxes fixing the mistakes.

Now this is just the way I think when drawing the boxes, and it's by no means perfect, I'm still struggling with it.

Thanks a lot for taking the time to answer my doubts and for this critique. I was a bit scared that my work might not have done an enough job to move to the next lesson.

For the questions, I'll follow those guidelines: short paragraphs, and very specific (to the point).

I will, I will, and you're right about me going back to trying to control the contour when applying line weight, especially on curved lines. Will work on that, I've been practicing a lot of ellipses and the ghosting method for straight lines, but not so much for curved ones on my daily practice. And I think I will also include those last two exercises on my daily warmup, the form intersections, and organic intersection because I feel like my mind is close to figuring out something about them, don't know exactly what it is thou. I saw the diagram about the sausage forms and the contour lines, and it hit me, it's so much clear now, and this got me thinking about the fact that I'm in no place to critique objectively my own work yet since I couldn't see that before, like some kind of selective blindness, and I studied the forms I drew trying to figure out if I understood the exercise and such.
