Hey there, looks like i'm a bit late with this but let's give it a shot with critique :)

Starting with lines and super imposed lines you clearly and nicely start at 1 point with the more straight ones but with the heavy curves ones i see some fraying on both ends. Placing a dot to start work with that. On the ghosting lines i see slight arcs that are easily to take down when you consciously go into the opposite direction of the way you want to arch towards. other than that, these lines have confidence and is great to see!

I'm guessing you used the ghosted planes for the ellipses in planes so i will cut the ellipses in planes a lil early. The planes have a bit less confidence here. Keep on ghosting until you are sure and confident that line will stay in place! For the ellipses you want to be sure that the ellipse touches each side of the plane. For that you can ghost a bit slow at first to be sure you touch each side and slowly ghost faster until you are at a speed you are most confident and comfortable with and then you can make the ellipse so its nicely in the plane touching each side.

Moving on to the ellipses (not that i already started with that.)

The ellipses are a bit shakey here, keep in mind on the ghosting i typed about above when it comes to ghosting. Apart from that, the vast majority is nice and snuggly in bounds with each other and you went through each ellipse recommended 2 times (but 3 times is an option too if you aren't so sure you can get it with 2.)

Onto the funnels we go and you kept it all nice and snuggly in bounds and can see you kept most of them along the minor axis, nice! Only some don't seem to follow the axis like the one in the corner a good way to measure it is when the ellipse is cut in half along the minor axis. For funnels you also gradually make them wider along the major axis as they go away from the middle (where if you make the major axis stick out a bit to be visible enough you might be able to see easier how to make them follow the axis more to be aligned.)

The ellipses themselves still have a bit of the same problem from the tables of ellipses but i see some improvement here.

And the last part, the boxes.

You've done a solid job on plotted perspective. I only see some angled lines with the ones you started but no biggie, those will be ironed out as you go on with Draw a Box.

Rough perspective i see the longer boxes have a bit of an arch but that's understandable at this point. For the width of the box, keep in mind that with 1 point perspective the height and horizon lines are perpendicular to the horizon. The vanishing point is so far away that the lines are straight lines.

Rotated boxes (by far the most difficult thing in lesson 1 if you ask me.)

They don't seem to rotated as much. When a box rotates it's vanishing point changes. The sharper and more distorted the angle becomes, the closer the vanishing point is like this visual example on the site it moves a bit fas but if you look closely as it rotates you can see how the vps work when rotating. Gaps also look somewhat inconsistent. You might have guessed at some points here.

And finally, organic perspective.

For the most part the boxes look the be the same without much different angles. Variety can be a good thing, especially when you do the 250 box challenge.

For overlaps you can do ateensy bit of lineweight by going over the part that overlaps again to show what goes in front of what. On the second page (but i'm guessing it was the actual first page) i see a lot of inversion making the boxes look like an isometric room. Vps go away from you, not towards but you ironed that out on the previous page on imgur.

You had a great start and got a bit shakey towards the end and picked yourself up again like a warrior!
