Hey there Llen! Starting off with your superimposed lines, these are looking nice and confident. You've taken the time to line your pen up with the starting point most of the time, which has limited fraying to one end of the line.

Next your ghosted lines and planes are looking good. Straight and confident and in the case of your ghosted lines, quite accurate to boot. There is a small amount of arcing present in some of your lines which you might like to work on pulling back by consciously trying to arc a lil in the opposite direction.

Onto your tables of ellipses - these are looking confident and for the most part you've smushed as many of them in there as possible. There are areas where the gaps between them get a bit loose, so make sure you're trying to keep them butted up against one another.

Your ellipses in planes are looking fantastic. The ellipses are very confident and they hit the four sides of the plane more often than not. Basically, a very well executed exercise, well done.

Finally, your funnels are off to a good start. You've gotten some good alignment in places and your ellipses are confident like usual. I did notice that when you skew off the minor axis, you tend to do so at roughly the same angle, so it's possible you may need to rotate your page and approach it from a different angle to help you align it to the axis. Also if, like me, you have a tendency to tilt your head while drawing, this can also contribute to skewing.

Next your rough perspective is off to a good start, you've made a clear effort to keep your horizontals parallel and verticals perpendicular to the horizon line. There are a few signs of rushing, particularly in the first frame, which has accentuated the arcing of your lines and causing them not to connect much of the time. Make sure you're taking the time to plan out each and every one of the lines of your box - one line is one unit of time, one box should be 12 units of time. It's clear you took more time on the second page, which has improved the accuracy of your convergences a lot. Where your estimations do stray, they tend to be the boxes further from the vanishing point, which is completely normal.

Your rotated boxes have got tight, consistent gaps throughout, which is great to see, as this gives you the best chance of estimating where the next box should go. There's a good degree of rotation however most of your rotation occurs on the outermost boxes, which results in a kind of squarish looking ball. That said, this and organic perspective are simply designed to introduce you to a new spatial concept that you can explore further in the 250 box challenge, rather than any expectation of perfect execution.

Finally, your organic perspective compositions have a nice amount of depth to them. You've overlapped your boxes in places which is quite effective at conveying a sense of 3D. It does feel in a few places like you're possibly still being a bit haphazard with your lines in places, so don't forget what I said about investing time into each line, particularly as you move into the 250 box challenge. There's some signs of distortion and divergence in your boxes, which is entirely normal at this stage and is again what you will work on moving forward.
