added comment inHow to Draw Cylinders and Ellipses
I was thinking again after watching the introduction to the ellipse.
Although an ellipse is used to draw the circle in perspective.
A circle in perspective is really an oval because the circle and circle in perspective use the same centre, meaning the nearer half is larger than the further away half, which would be smaller, and would not pass the fold test.
Any advise would be appreciated to confirm this thought.
Thanks

Yes, except I think the nearer half will be smaller than the far away half for some ungodly reason.

Will someone please explain to me how one figures out where the major axis crosses? I know it’s perpendicular to the minor axis (which vanishes into the vp) but I don’t know how to figure out where the heck to put it along the minor axis. I am literally having nightmares about this. 😭😭😭😭
I was wrestling with this as well. Johannes’ animation is helpful but the critical piece I was missing is that the major axis always shifts away from the center point along the minor axis… IN THE DIRECTION TOWARD THE VIEWER!
in Stan’s video this is easy to see as the major axis is shifted toward the upper right corner of the box which is closest to the viewer.
The amount it shifts off the center point is strictly a judgement call and intuition as there’s not an accurate way to locate it without math.

I'm sorry my posts have added to your confusion.
I too struggle with this topic.
Johannes S, posted a great circle / ellipses animation.
From the animation I my understanding is:
A circle in perspective is an ellipse.
Draw an accurate ellipse on paper and cut it out.
An ellipse has 4 equal quadrants.
An ellipse when correctly drawn it should pass the fold test along both axis.
If folded along the major axis both halves should match exactly.
If folded along the minor axis both halves should match exactly.
If folded in quarter all quadrants should match.
Observing Johannes's Animation
As the cube tilts away, the yellow circle centre line ( it becomes the Ellipse Major Axis) moves toward the viewer. As this happens the circle changes into an ellipse.
Viewed as an ellispse with repect to the moving yellow line
the yellow line moves toward the viewer, to maintain the ellispses'
major axis, minor axis and it's four equal quadrants.
Notice also, as the cube rotates 90 degrees, so does the minor axis
maintaining the conditions required by the ellipse.
When viewing the circle as a circle in perspective.
The circle centre is determined by the cube diagonals intersection.
This is observed as the front half being larger than the back half of the circle.
Remember:
A circle in Perspective, is viewed with respect to a centre line drawn through the circle diagonals (cube diagonals) intersection.
Not with respect to the ellipse major axis.
The major axis is only used to create the ellipse.
Fingers crossed Marshall Vandruff will cover Ellipses and Circles in Perspective
in his Perspective Course.
If my observations above are wrong, I'd appreciate feedback, thanks.

Doing these is oddly relaxing. I feel like the more exercises I do the better I grasp the concept (ha who’da thought), but I gotta stop here bc my goal isn’t to be really good at box hands. Any critique is greatly appreciated.

Your mannequin hands have been looking great! Glad you found them relaxing and not stressful. It seems like you've really gotten the hang of this exercise.
Just two very minor critiques: Be careful not to break the joints too much, I think it would make more sense for the tip of pointer finger to point in the direction of the flow of the rest of the finger in this one. Also, tapering the fingertips a bit more when they are coming directly towards the viewer will help the perspective.

Level two project. I picked the two faces I hated the most, or rather the ones I had the most trouble with, while completing the level 1 assignment. I tried to really nail the proportions and placement of the features, so much so that I feel like I put the perspective boxes on the back burner - but they look ok! Onward.

Level 1, basic box construction with some features bc I have no self control. It was difficult to picture the box around the whole cranium, I kept chopping off the top of the skull in an attempt to account for hair (bald man was nice to draw) and I kept squishing the boxes vertically. It was a helpful exercise though, and now I see a box around everyone’s head when I look at them.

this was v fun!! It’s such mindless drawing, great warmup for lines and perspective. Also @Stan Prokopenko - pls drop the soundtrack, v relaxing!!

will someone help me figure out what I’ve done wrong with these books? It looks like they’re just floating on top of each other, instead of following Newtonian physics. 🤡

It looks like the balance would be off, maybe try moving each book more in towards the center of the stack. Pay attention to where the side plane of the book touches the top plane of the one below it. I would also shrink the size of the top book (optional, normally the largest book wouldn't be on the top of the stack). I tried to illustrate what I'm talking about, hope that it makes sense 😂 Your perspective lines look fine to me.
