Overall your intersections are progressing well. As you read in that other student's feedback, at this stage we don't expect students to be knocking this exercise out of the park with a perfect score - rather, it's normal for students to still struggle a fair bit with intersections involving curving surfaces, while being generally pretty solid with those only involving flat surfaces.

In your case, you're not too far off the mark with the curving surfaces (as shown on the corrections here you're generally going in the right direction, but just need to be thinking more specifically about the surfaces at play for the specific intersection you're dealing with, about how the intersection line you're drawing needs to sit along the surface of both forms simultaneously), and your intersections involving flat surfaces are generally coming along well, with the only notable issue being this one here where you included a random corner for what appears to be no specific reason. Usually when students take actions that don't have a clear reasoning behind, it's because they're relying more on trying to work from memorizing certain kinds of relationships between forms, or trying to intuit out the relationship without necessarily looking at the specific forms at play in front of them.

To that point, this diagram is one that I generally share at this stage - it shows how we can be thinking about the specific forms that are intersecting, and the particular pairs of surfaces that interact at any given point along an intersection line. Note in particular how we're identifying which cross-sectional slices of the sphere are relevant to the different parts of our intersections, and how it helps us break down the nature of the intersection in - and I've used this term a lot in this feedback - more specific terms.

One last thing, I wanted to respond to this:

I opted for more dramatic perspectives because having at least 1 Vanishing point on paper made it easier to get accurate. I am not sure if I could have used a different angle while still having a vp on paper.

When an exercise puts a particular kind of problem in your path (like using boxes whose vanishing points are all farther off the page), purposely tailoring the exercise to avoid that problem is the opposite of what you should be doing. These are exercises - avoiding your weaknesses is robbing you of the opportunity to address them and work through them, or at least recognize that they need to be addressed.

More largely though, if you do struggle with boxes with far off vanishing points, that might suggest that you're not practicing the freely rotated boxes with line extensions from the box challenge as part of your warmups, or at least not as much as you should be. It's important that you include all of the exercises we've introduced on a regular rotation so you're continuing to develop all of those areas, rather than leaving them to fall behind, only to need them further into the course.

Anyway, I'll go ahead and mark this lesson as complete.
