Hi there, TA Meta here to review your work, so let's get started.

Beginning with your superimposed lines, these are looking straight and confident. You've taken the time to line your pen up with the starting point, which has limited fraying to only one end of the line, which is good to see. Next, your ghosted lines and planes are beautifully straight and confident and I don't have a lot to say on them as accuracy will come with mileage, just focus on keeping them confident.

Next your tables of ellipses continue the trend of confident linework, it's good to see that you've drawn through all your ellipses 2-3 times and packed them in there nice and tightly. I did notice you struggled a little with the smaller ellipses, which are less confident. Make sure you're ghosting these out and executing with your shoulder. It will take a while to gain the fine control over those muscles to execute the smaller ellipses, so make sure you keep practicing.

Your ellipses in planes are also looking pretty smooth and confident as well and you haven't sacrificed this confident flow for accuracy.

Finally, your funnels are looking pretty confident and you've done a pretty good job of aligning them to the minor axis for the most part, in spite of slight inaccuracies with the positioning of the axis. There are a few instances where they're slightly skewed off and in some cases where they're popping out of the funnel. The one second from the right is probably the one with the best alignment overall on this page.

Moving onto your rough perspective now and you've done a pretty good job keeping the horizontals parallel and verticals perpendicular to the horizon line, particularly on the front planes. Your estimation of perspective is pretty good here, and where it strays, it generally does so in predictable and expected ways. Your line confidence did slightly decrease here, which we see quite a lot, so make sure you're taking the time to plan and execute your lines as confidently as possible.

Next, your rotated boxes are off to a good start, your line confidence here is great and you've done a good job keeping the gaps between your boxes consistent. You haven't managed to rotate the boxes all the way, instead causing your next box to follow the same vanishing points as the previous box. This is pretty normal, because our brains resist rotating boxes like this, because they want to follow the exact same vanishing points of the previous box.

Finally, your organic perspective is doing a pretty good job of exploring the 3D space set by your compositions. I think you could've pushed the variation in the size of your boxes a little more to convey a more dramatic sense of scale in the compositions. Additionally, your boxes are showing some signs of divergence however that is completely expected and normal at this stage because these last two exercises are intended as an introduction to some new spatial problems and is a convenient segue into the 250 box challenge.
