Hi Shapudl! Overall you've done a great job, but there are a few things I want to comment on so you can keep improving, let's go!:

Starting with your lines they are good overall, pretty confident and smooth. The only issue I can see is that on the ghosted planes you haven't been plotting all of them. Before drawing any line you first need to draw the starting and ending dots of it, otherwise you won't be able to ghost it properly.

You also have a great variety through the pages, but you could try to do more super long ghosted lines/planes, as you haven't done many of them.

Moving onto your ellipses they are a bit wobbly (they tend to be non symmetrical and tapering towards one side so remember that they have to be symmetrical). Remember that in ellipses as well as lines you should try to draw them as confident as you can, so don't hesitate in sacrificing accuracy to get them smoother and more confident.

On the ghosted planes I think you have a tendency to change the ellipses to make them fit the plane. It's important that you don't do this because ellipses have to be symmetrical, so their shape can't change. Always focus on drawing the shape of the ellipse confidently. If you want to make the ellipse touch the contact points the only things you can change is its position and its degree, nothing else.

Though I can see they get a lot better as by the time you get to the funnels most of them are super confident so good job! Only problem on the funnels is that sometimes you aren't aligning the ellipses to the minor axis. Remember that the minor axis should cut the ellipses in 2 identical halves, and don't hesitate on ignoring the curves if you need to.

Finally in your boxes a few things:

-Overall the lines are super confident as before, which is great! But in a few cases I think you tried to make the lines touch the ending dots by making them a bit wobbly. Remember that just like before your first priority is to make them confident and straight, so don't worry if that means you have to sacrifice accuracy. Try to think of each line as an individual exercise.

-On rough perspective you're doing a great job at keeping lines vertical and horizontal and are making pretty good guesses of the perspective of the depth lines, keep practicing like that and you'll improve in no time! Only thing I want to say here is that before drawing the lines you can use the dots you drew to ghost and check if the line is going to hit the vanishing point or not. If it's not gonna hit it you can change the dots and try again. It helps a lot with getting the guesses more accurate.

-On rotated boxes you're doing a great job at rotating the boxes and keeping the corners together, good job! Only thing here is that some of the sets of parallel lines aren't converging, but don't worry about it as you'll learn it on the box challenge.

-On organic perspectiuve you're making a pretty good attempt, and I'm glad to see that your lines are still confident. Just a few things:

-Try to draw through all the boxes, if a box covers another box, you should still see the covered box entirely.

-Sometimes you repeat lines. No matter how off a line is don't repeat it, as it'll only make the drawing messier and encourage bad habits.

-Sometimes you don't draw starting and ending dots for all lines, make sure you do it as it's super important for the ghosting method, even if the lines are going out of the frame.

Overall like I said you've done a pretty good job, so I'll mark this as complete. Don't forget to do warmups from now on and good luck with the box challenge, keep up the good work!
