Your lines is off to a good start! you clearly have confident in your lines and I did not that much of a fraying as well, that's mean you are up to the right path. You also keep your confident through the plane exercise as well, which is good.

In the ellipse in plane exercise you seems to struggle a bit with drawing ellipses, we did not want to see any wobbly line due to lack of confident. Just keep in mind that smooth and confident lines come first, whenever your pen touch the paper there is no room for any mistake, is there is its still fine. Just keep practicing and use ghosting method for every line and you will started to develop accuracy afterward.

In your table of ellipse exercise, I see that your ellipse is improving throughout the exercise which is nice. However, I see that you are not drawing through some of your ellipse, results in some of them seems wobbly and not smooth. Just keep in mind to drawing through every of your ellipse.

In your funnel exercise, I see that your ellipse having almost same degree throughout, keep in mind that toward middle the degree of the ellipse will be smaller compared to the one far from the middle.

In your rough perspective exercise. I see that you seem to lose your confident a bit. It's might comes from you prioritize accuracy before smooth and confident line. Just as I mentioned in earlier you have to keep your line SMOOTH and CONFIDENT. Always use the ghosting method for every line and If there is a mistake it's fine, we all make mistake here and there.

You did pretty decent job in Rotated box exercise. I like that your line is confident and you also go through your line again to separate each box from each other. I also see that you are struggle a bit in the corner boxes, which is perfectly normal. you will have plenty of time practicing in 250 boxes challenge and I recommend to get back doing the last two exercise after that to see how much you have improve.

In your organic perspective, my major complain is that the perspective of the boxes is off. For a reminder, when drawing boxes in 3 points perspective there will be 3 sets of 2 lines (3 lines if you are drawing through a box) that converged into the same vp. But you do not have to worry about this right now because its will be much more clearer after you have done the 250 boxes challenge.

Overall, pretty solid submission. You have grasp the concept of the lessons very well, just keep in mind that smooth line comes first accuracy comes later. And that's it, I will mark this lesson as Complete and good luck in 250 boxes challenge!
