Thank you for taking the time to critique my work! Really appreciate you numbering the points I need to improve on, made it easy to spot among the entire critique.

Plotted perspective

"Some of your vertical lines in the Plotted Perspective exercise are not perpendicular to the horizon."

Could you point out where these non perpendicular vertical lines are? Are you referring to the ones for the back edge at the end of each box?

Rough perspective

"The front and back faces of your boxes in the rough perspective exercise should be rectangular (composed of true horizontal and vertical lines). It appears some of your lines are at arbitrary angles."

Thank you for pointing that out, I think I focused too much on ghosting to the VP on some of them that I've forgotten to make them rectangular.

Rotated boxes

I've kept your pointers in mind as I worked through my revision. You can find it at the last image on the same imgur link here (https://imgur.com/a/UQmeHHc).
