Hello strawberryj_! Overall you've done a good attempt, but there are a few things I want to comment on, let's go over them section by section:

Starting with your lines they start off a bit wobbly on the superimposed lines, but they get better soon, and overall 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!

Sometimes I can see a bit of fraying at both ends of the lines, make sure that whenever you draw a line you carefully place the pen at the starting dot so the lines can fray on maximum one end.

You also didn't draw many lines on the ghosted lines exercise. It doesn't happen in other exercises, but just as a reminder try to always more or less fill the pages so you get enough practice and we can assess the exercises better!

Other than that the accuracy is already pretty good, and your lines are still confident even in the ghosted planes, so good job! Keep it up like that and the accuracy of the lines will keep getting better and better

Moving onto your ellipses they're confident just like your lines on the lines section, which is exactly what you're meant to do! The accuracy on them is good as well just like in lines.

Main thing is that sometimes the shapes of your ellipses get a bit uneven, being for example a bit pointy in one end and rounder in the other. It happens specially on the ellipses in planes as well, so 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:

-You're still maintaining confident lines even in the box section, but sometimes they get a bit wobbly, specially on the smaller lines, so try to loosen up a little bit so they end up being fully confident.

-Sometimes you repeat lines that missed the ending dot, but just like in the line section make sure you don't repeat any line even if they miss. Try to think of each single line as a single ghosted lines exercise. In case you missed the dot, if the line is confident that means that you did the exercise well, so you have nothing to worry about.

-On rough perspective the main thing is that you aren't applying the line extension method explained on the exercise. You're starting to make some good attempts at the perspective lines, but it's important you do the extensions to see where you're wrong and to improve!

-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 you haven't drawn through some of the boxes on the outer ends, so make sure next time you attempt it that every box has the 12 lines!

-On organic perspective you've done a great attempt planning your lines and drawing them confidently. Make sure you plan even the lines that get outside the page, it's important to draw starting and ending dots before drawing each line to apply the ghosting method properly.

Remember also that you can add lineweight to the parts of outer lines that overlap with other boxes to clarify which ones are on top and which behind, so give it a try next attempts you have at the exercise!

Lastly the perspective on the boxes has issues, but that's not a problem as you'll work on them on the box challenge.

Overall like I said you've done a good attempt, but I want to make sure you know how to do the rough perspective exercise and can handle the line issues I mentioned before moving on, so I want you to extend the lines of the previous pages, and then do 1 more page of it, make sure you extend the lines!
