very good

Rough perspective:

shaky lines, some lines lead to the opposite point from the vanishing point, do not forget to use the ghost method

Tables of Ellipses:

ellipses often run over each other, the second sheet is worked out better, well done

Rotated Boxes:

Read "As things move farther away, they appear smaller" https://drawabox.com/lesson/1/7

when moving away from the vanishing point, not only the object decreases, but also the distance between its vertices. Do not forget that the angle that is further into the depth will be closer to the center of the square as distant objects decrease. Therefore, your squares at the corners have an irregular shape

Organic perspective:

this video will help you better understand the space https://youtu.be/bv3Yvfouf2o?si=HOCfkwKi4weQbqkc

Ghosted Planes:

overall not bad

Ellipses in planes:

in small planes there are beautiful ellipses, in large planes there are bad ellipses (sharp bends), conclusion: instead of large planes, use medium-sized ones until it gets better

Funnels:

my ellipses don't look any better, so I don't know any advice on how to improve it, I think only daily practice of this exercise for 10 minutes a day? =)

Superimposed lines:

arched and shaky lines, use your shoulder when you draw, do not put your hand on the table, make sure fast lines, do not forget to use the ghost method

Ghosted Lines:

It looks like you are drawing your lines a bit to far they should stop at youre end point. They also look a little wavy and not on point.Try to start with some shorter lines about one third of the page and go from there, its hard I know.

 Ghosted Planes:

 Same as with the Ghosted Lines your lines are a bit to long and wavy.

Try some smaller planes and then go up in size and do them on every warm-up together with the ellipses and you will se improvement fast.

Funnels:

The ellipses are combed too much, the second and third stroke diverge greatly from the first stroke, try to trace along the contour already drawn

Rough perspective:

????? ??????, ????????? ???? ????? ????? ? ????????

Superimposed lines:

your lines are curved in an arc, perhaps you draw with your elbow when it needs to be done from the shoulder, the lines diverge greatly towards the end, do not forget to use the ghost method

Ellipses in planes:

You drew too large planes, and therefore when your ellipses could not fit, you bent them, try using smaller planes.

Organic perspective:

To complete this task, I recommend watching this video to better understand the boxes in space

https://youtu.be/bv3Yvfouf2o?si=_upIGRrM4cc-xp7-

I am a beginner myself, so I will not put this task as completed so that more experienced people can check it, but I think you can start the challenge in 250 boxes and do not periodically perform "Superimposed lines" and "Ellipses in planes" for 15-20 minutes a day

I don't speak English, I hope the text is clear

add a working link

there is only a page with Superimposed Lines

in the lesson of the Ellipse Table, ellipses have a shaky line, pay attention to this and practice it.
