Hello Jam! You've done a good job overall, though there are a few important issues I want to comment on, let's go!:

Starting with your lines they're confident in general, good job! Though they do get a bit wobbly at times so try to keep an that. The first priority with lines is to make them confident and straight, so don't worry if you need to sacrifice accuracy make them straight.

Here's one example, top line is a level 1 line, and bottom line is a level 0 line. This is because a confident line will always be better than a wobbly line in these exercises.

Another thing is that your dots are a bit too big. Try to make them smaller so it's easier to assess the ghosted lines exercises.

Your lines also fray on both ends at times. Make sure you place your pen at the start of each line carefully before drawing them so it doesn't happen.

Moving onto your ellipses they're very confident overall, great work! They get a bit messy sometimes so try to stick to drawing through them 2 times if you can.

The only problem with the ellipses is that when you draw them smaller I think you have a tendency to make them a bit wobbly. Make sure you approach even the smaller ones ghosting and drawing with the shoulder if you aren't already.

Lastly on the funnels sometimes you aren't alligning the ellipses to the minor axis. Make sure you aim the minor axis to cut the ellipses in 2 identical halves even if you have to ignore the initial curves.

Finally in your boxes a few things:

-Lines get a bit wobblier on them, same thing that I said earlier applies here. Make sure you always draw your lines confidently so at least you get level 1 lines. And try to draw the dots on the lines smaller as well.

-You're also making a good attempt in the guesses on the perspective lines in rough perspective. An issue less important than line confidence you have is that sometimes you seem to have trouble 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 rotated boxes you've made a good attempt managing to keep most of the boxes together and rotating most of them. But some of the boxes are bit too far away, specially on the corners. And some of the boxes that are farther away aren't rotating as well. So try to keep an eye on that in future attempts.

-On organic perspective you're having issues with the perspective but that's not a problem as you'll work on it on the box challenge. Main thing here and on rotated boxes is that you're repeating lines quite a few times. Whenever you draw a line, accept the result. Don't redo the line even if it goes wrong, keep going to the next line.

So before moving on, I want to make sure you know how to draw confident lines on boxes, so I want you to do 2 more frames of rough perspective and 1 more frame of organic perspective. Make sure you focus on getting all your lines to be at least level 1 and that you don't repeat any line. Good luck and keep up the good work!
