Hello Partly_macleody! Overall you've done a very good job, there are a few things I want to talk about so let's cover them through each 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!

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.

Other than that you're planning every line you do very well and taking care drawing every one of your lines. Accuracy is good as well already so good job! Keep practicing like that and it'll get even better.

Moving onto your ellipses they're confident just like you did 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. There are some places in which your ellipses don't get to touch the top or bottom lines, but they're just a few, keep practicing like that and they'll keep getting more accurate more consistently.

You're also not getting confused on the ghosted planes and you're drawing the ellipses as confidently as you did in the previous section, so nothing to say here neither!

Lastly on your funnels sometimes you aren't aligning the ellipses to the minor axis, which happens specially on the angled ones. 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.

The ellipses on the funnels get a bit too separated at times as well, make sure you're always aiming for the ellipses to touch together so they don't end up floating.

Finally in your boxes a few things:

-Lines are just as good as they were on the lines section! I can see you took your time with them and didn't get confused by the boxes, so good work!

-Sometimes you repeat lines that missed, but just like in the line section make sure you don't repeat any line even if they missed the ending dot. 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 you're making some very good attempts overall at the perspective lines, but sometimes you have a bit of trouble keeping height lines perpendicular to the horizon line, width lines parallel to it, and specially some of your depth lines are a bit off. 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!

-On rotated boxes you've done a great attempt. 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're already boxes with some very good attempts at the perspective! Main thing here is that I think you aren't drawing starting and ending points for all of your lines. If this is the case make sure you do it because it's super important for applying the ghosting method properly.

Last thing is that some of your lineweight lines are a bit wobbly, make sure that when you add lineweight you do it with confident lines as well, as if it were a ghosted line exercise, and make sure you only add lineweight to the parts of lines that overlap with other boxes, not to the complete lines.

Overall like I said you've done a great job, so I'll mark this as complete. Remember to always plan all of your lines and to always approach lines confidently even if they're for lineweight, and move on to the box challenge!

From now on you need to do warmups before every session, so don't forget about them! And make sure you ask any questions you might have. Keep up the good work!
