that's what I think, your key mistake is that you don't understand - that closer lines are always longer. You have drawn the vertical line closest to you. So all other vertical lines should be shorter. You draw the top faces closest to you and the bottom ones parallel to them should be shorter because they are further away from you. For a better understanding, it may be worth using a more dramatic perspective first.

Thanks for your critique!

Your lines very good!)

I think you have completed all the exercises well and with understanding and you can proceed to the next step.

In the Rough Perspective exercise, your lines are slightly shaky. Though your wobbly lines seem to get much more consistent later on.

I liked how you did the organic perspective exercise. Although I notice that you forgot to rotate the boxes at the far end of the curve, in the first sheet, but corrected in the second sheet

On all of the exersises I think you did a very good job.

I would recomend moving on to the 250 box challange

In superimposed lines, I saw that many of the lines curve down in an arc, I assume they were drawn through the elbow pivot point.

In the rough perspective exercise, you used guide lines without tracing your lines. Thus, you have reduced the effect of this exercise, because you did not see where your lines actually point. https://drawabox.com/lesson/1/16/step6

We are not plotting these red lines back to the VP - just to the horizon line. This will show us a concrete idea of how far off we were.

There's a good chance that you'll find them not intersecting with it at the vanishing point, and you may also find that the further away your boxes are from the VP, the further off they are in their alignment. This is totally normal, and it helps a great deal to go over our work in this manner to help identify where our estimation of perspective tends to drift, so we know what to focus on during our next attempt.

In the tables of ellipse exercise, it was assumed that the ellipses should touch two borders, I note as an mistake that there are sections where the ellipses are made without touching two borders.

In rotated box exercise 1 i saw mistake: Not actually rotating. https://drawabox.com/lesson/1/17/notrotating

The corresponding edges of boxes are all converging towards roughly the same vanishing point. The same error can be traced in the second exercise along the horizontal axis. Perhaps because of this, you also got large gaps at the far end of the boxes.

You also didn't make good use neibouring edges to figuring out the angles of your new box edges. https://drawabox.com/lesson/1/17/step7

But overall you did a good job and I recommend starting the 250 box challenge

In Superimposed Lines exercise i saw the "Fraying on both ends" mistake and wobbling on small lines and curves. Though your wobbly lines seem to get much more consistent later on the Ghosted Planes exercise

The ellipses tended to go beyond the boundaries In the funnel exercise.

In the organic perspective exercise, it was sometimes difficult to understand where the foreground and background were, the cubes often had a similar size. In addition, in some compositions you have not avoid a more dramatic background perspective.

On all of the other exersises I think you did a very good job.

You make pretty good straight lines in all exercises.

I would recomend moving on to the 250 box challange.
