Hello Bearwerm! Overall you've done a good job, but there are a few important things I want to go over, let's go through it section by section!:

Starting with your lines you're doing a pretty good job drawing them confidently and committing to drawing them straight even if they're going to miss on the ghosted lines. Some of the lines are a bit wobbly, so keep trying your best to draw them confidently though! On the superimposed lines you're having wobblier lines, so try to approach them like you did on the ghosted lines in future attempts.

Another problem you have is that when starting a line, you should carefully place your pen on the start of each line so only a maximum of 1 end can fray. Plan each stroke you make carefully.

Last thing is that you aren't drawing starting and ending dots on each line you draw on the ghosted planes. Be careful with that as it's pretty important for applying the ghosting method.

Moving onto your ellipses you're mostly drawing them confident as well and doing well fitting them within the bounds of the tables of ellipses, but they're overall a bit stiff. Try to loosen up a bit more to get them as confident as you can draw them. Just like with lines our priority is to make them as confident as we can, accuracy comes after. Sometimes you're also drawing them through only once, make sure you always do it twice at least.

This applies as well to the ellipses on ghosted planes, which I think they're a bit wobblier than the others. You might be thinking that the centre of the ellipses is the same as the centre of the planes, but this is not the case. Ellipses have to be symmetrical and have the same form regardless of where they are, so the only things you can change is how wide the ellipse is and which position it is in.

Lastly on your funnels sometimes you aren't aligning the ellipses to the minor axis. Make sure you always aim for the ellipses to be cut symmetrically by the middle line even if that means you need to ignore the initial curves.

Finally in your boxes a few things:

-Overall you're drawing your lines more hesitantly and drawing over them a few times. Make sure you apply the ghosting method like you did on the ghosted lines exercises. They might be inside boxes, but they should be approached just like the lines. Make sure you don't repeat lines neither even if they go wrong, as it will make the drawing messier and encourage bad habits.

-On rough perspective you're making a good job drawing the boxes apart from the repeating lines issue, but you seem to have trouble at times keeping height lines perpendicular to the horizon line, and width lines parallel to it. I know it's hard, but make sure you always are aiming for it. You can check if the starting and ending dots are correct or not, and if you find that they aren't you can change them. You can put down as many dots as you want as long as it's before drawing the actual line.

-On the rotated boxes you've done a good attempt! The boxes are rotating and they are close together. The main issues apart from the line issues i mentioned is that you haven't drawn the boxes on the outer edges, so 4 of them are missing. Make sure you draw them even if the viewer isn't going to be able to see them. I Know it's tough, but make sure you finish the exercises.

-Lastly on organic perspective the main problem is that you aren't applying the ghosting method. Make sure you always start drawing each line by drawing the starting and ending dots. Otherwise you can't ghost it properly. That said you're already making some good attempts at the perspective of the boxes, good job!

Overall you've done a good job throughout the exercises, but before moving on I want to make sure you know how to plan your lines properly on boxes and that you can draw your lines in boxes as you can do them when they're alone, so I want you to do one more page of rough perspective. Good luck and keep it up!
