yo,

Lines:

Superimposed Lines - not sure where is the beginning of the lines.

Check this link https://drawabox.com/lesson/1/9/fraying

Ghosted Lines - you were doing them to slow which make them unstable and wavy. Same for ghosting planes.

Ellipes:

table of ellipses - you've forgotten about the table. It was an indicator of how big your ellipsis should be. What's more You should do it with ghosting method.

Ellipses in planes should be done with ghosting method.

Funnels, looks good imo.

Boxes:

In Plotted Perspective you've underlined lines unnecessarily. It's makes your boxes looks messy.

(btw it's not a part of the course but when you are doing hatching, you should make marks only in one direction, avoid waves like in middle box of third attempt to exercise)

In Rough Perspective, lines that you are doing with your ruler should overlap freehand lines. Thats the main point of the exercise. Again unnecesary underlines.

Rotating Boxes - you should watch (or/and read) the whole lesson one more time (at least) and get familiar with this link

Organic Perspective - Your boxes were not done with ghosting method. But they are rotating and growing properly ( i think )
