Alright let's see...

- Superimposed lines

Your tapering on the first one is a little much. Also I've noticed your bended lines have tapering on two sides. It seems you've noticed it yourself, as your second page is much better. I do still see some wavyness in your lines. I'm curious if this is caused by drawing from the elbow? They are not the small wobbles like drawing from the wrist but they are not completely straight either.

Ghosted lines

There is some bend in the lines. This could be because you were drawing from the elbow instead of shoulder, or because its a conditioned movement. In the latter case you could try to purposely draw bended lines the other way, so your brain will average it out to a straighter line.

Tables of ellipses

There are some really good ellipses in there, but also some less good ones.

When you draw through your ellipses, you have a tendency to make the second time around smaller. try to give as much thought and control over your second time going through the same ellips as the first time, and try to keep it approxomaly evenly sized.

You also tend to draw the ellips more left than inteded I notice, causing you to overshoot to that side or leave too much open space on the right side. Maybe you could use the same trick as with the bendy lines by drawing a couple of ellipses purposely more to the right as where it should be, so your brain will eventually even it out and you will draw the ellips on the intended place more easily,

Also I highly recommend drawing a border around the tables so your circles never touch the end of the page, I'm guessing this also caused you to subconciously to move the circles more away from the border so they overshoot or leave to much space. By drawing a border you take away the anxiety of accidentally moving your pen outside of the paper.

Ellipses in planes

Same thing as before, when you draw through you tend to make the second time way smaller and just really inconsistent. Also you drew through it too many times. Two is enough.

I think you did improve a lot on the accuracy of drawing within the borders.

Funnels

The accuracy of your ellipses are looking really a lot better then earlier. However your funnels could be mmore funnel-like by making the inner ellips more narrow/flat and then progressively making them rounder towards the outside. Also try to draw them less skewed.

Plotted perspective

Perspective-wise your boxes are correct and good. Your vertical lines could be better. Did you use a ruler for those? Also don't forget you can rotate your page if you want.

Rough perspective

You were supposed to draw the coloured lines over your already drawn lines, so you could see how far off from the vansishing point they landed. Now we can't really see where your common errors are. your linework is a bit bendy still, aslo your boxes tend to skew the right way. this was also a common trend in your ellipses. i think you could benefit from rotating your page more.

Rotated boxes

You've made the same mistake as I did I see. You accidentally moved the vanishing point the wrong way so now it looks like your "ball" of boxes has inflated on the sides. At least that is what I think happened. Basically the vansihing point is supposed to move more to the right as the box moves more to the left, vice versa. Now the vansihing point is going the same direction as the boxes causing more foreshortening.

Organic perspective

Is see only one page. Did you forget one or did it accidentally not upload?

Some of your boxes are two point perspective instead of three point. Also your boxes seem to not be rotating that much. I would suggest starting every box with drawing the closest edges facing you (looks like a sort "Y" shape) and then drawing your other lines. If you focus on that "y" shape you can see the rotation more easily. Basically rotate the "Y" shape then the rest goes naturally. On the homework page of this exersise it is explained how the "Y" shape works.

sooooo that was a lot. I hope this was in any way usefull. I'm also new in this course so I basically repeat a lot of the stuff told in the course itself and I still make many of those mistakes myself. Good luck!
