Hello Lyra! Overall you've done a good attempt. There are some things I want to comment on, so let's go through each exercise section by section!:

Starting with your lines you're doing a great job committing to your lines and drawing them confidently even if they're going to miss then ending dot, which is just what we're looking for! They also start being a little bit wobbly at times, but by the end of the ghosted plane exercises you've gotten a lot better and drawing them consistently confident, so keep it up!

You're also putting care on each line as they show by not fraying on both ends consistently! The only thing I'd mention here is that your dots are a little bit too big. Try to make them a bit smaller, more or less of the same width of the lines, so it's easier to assess the results of each ghosted line exercise.

Moving onto your ellipses you're drawing them mostly confident as well, though they do get a bit wobbly at times. Try to loosen up more and experiment a bit with speed as drawing them faster makes it easier to draw them confidently. The accuracy is also a bit off sometimes, so always remember before drawing every ellipse that they should touch the top and bottom lines of the tables of ellipses, as well as to touch the ellipses they have at their sides. Make sure you are also ghosting at the same speed you're drawing your ellipses, and that you ghost a few times more in general in the ellipses, it should help with the accuracy.

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 or that you should modify the elliptical ellipse shape so it touches the contact points, 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. Pay also attention to the angle of the ellipses as well. They have to be cut symmetrically by the line, so they can't be tilted.

Finally in your boxes a few things:

-Overall you're still doing a great job with confident lines in this section, but the main problem is that you have a tendency to repeat lines when they're off. Just like you did on the lines section, whenever a lines goes wrong leave it be and move on to the next line, every single line on each box is like a singular ghosted line exercise, thinking of them that way might make it easier, so give it a try!

-On rough perspective 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, so give it a shot!

You are also not drawing many boxes per page, try to fill the pages a bit more so you get more practice out of every page.

-On rotated boxes you've done a great attempt apart from the line issues I mentioned. Most boxes are rotated and all are kept close together, good job! The only thing is that some of the boxes on the outer ends aren't rotating, so keep an eye on that in future attempts at the exercise.

-Lastly on organic perspective you are also starting to make some great attempts at the boxes! There are still some boxes that have some perspective issues, but that's not a problem as you'll work on that on the box challenge.

Overall like I said you've done a good job, but I want you to make one more page of rough perspective so I know you can not repeat lines on boxes like you did on the lines section. Good luck and keep up the good work!
