Hello there I am QUAT but you can call me Quat, and I am going to critique your submission today.

So first of all lines: for the super imposed lines exercise, your lines don't look wobbly and they only fray on one side which is good.

For the ghosted lines exercise, your lines are quiet confident and they don't seem to arch, so good job on that.

For the ghosted panels your lines are fairly confident and even though there are some arching lines, they aren't common.

Next Ellipses: for the tables of Ellipses exercise, your ellipses look fairly confident but some of them are not very planned out so you should plan out better in the future.

For the Ellipses in planes exercise, some of your Ellipses are floating, which again you should plan better for the future, other than that you did a good job.

For the funnels exercise, a lot of your Ellipses are not aligned to the minor axis properly and I think that if you organized the page a bit better you could have added one or two more funnels.

Finally boxes: for the plotted perspective exercise, you seem to follow the instructions pretty well and there aren't any distortions.

For the rough perspective exercise, you made the mistake of guessing where the boxes should be rather than using the ghosting method to draw them roughly, also a lot of your lines are wobbly and you might need to redo this exercise.

For the rotated boxes exercise, your boxes don't rotate for the most part, and also the page is pretty messy and your lines are very wobbly, so yeah you are redoing this exercise too.

For the organic perspective exercise, your lines are quite wobbly and for a panel you leterally drew four boxes, so yeah I think that you are redoing this one too.
