Lines

Superimposed lines overall look confident. the fraying on the ends should get better with practice. Try maybe ghosting the line a few more times before drawing it. and or adding more speed when drawing in the line.

Ghosted lines look okay but they are not as confident as they could be. Here after plotting the line ghost the line until confident with the motion. Then draw in the line with speed from the shoulder. I think you need to add more speed when drawing in the line. The lines of the ghosted planes are also not as confident as they could be. I assume you rushed through them. Try and work line by line. Some lines look as though you drew them slowly , not super slow but not fast enough. Or maybe not from the shoulder.

Ellipses

A good number of your ellipses are executed with confidence. Some however are not. For example in the first funnels page. A number of the narrow ellipses are not confident. It looks as though you drew them slowly trying to make them fill a certain space. This slow drawing resulted in the wobbled and bends on the ellipses circumference. Or you could have omitted the use of the shoulder.

Then in the table of ellipses I see a number of them where you start drawing the ellipse then the drawing through of the ellipse is wider. As if you did not really know where you would space the ellipse then expand its radius by drawing out wider on the second pass drawing through. I dont think it is a problem but there is a better way. Which is ghosting your ellipses, ghost the ellipse in the space you want it to fill. This takes out the guess work. So in the ellipses in planes you ghost the ellipse touching all the points of the plane it must touch. Then once confident with the motion , draw the ellipse with speed. You do not have to worry about accuracy, ghosting takes care of that.

Now your focus is drawing a confident smooth ellipse with speed. This applies to all ellipses you draw.

In the table your ellipses should be touching with no gaps between them.

Ellipses in the planes look good for the most part.

Boxes

Plotted perspective looks good. In rough perspectibe remember that the vertical lines of the boxes are perpendicular to the horizon and the horizontal lines of the boxes are parallel to the horizon. Basically you can use the horizon as a reference for your lines as some of yours do not adhere to that.

For rotated boxing I would advise scaling the boxes size but other than that I see you are applying yourself to rotating them in 3D space.

Oraganic perspective looks good, I can see you plotted your lines good job there.

I will ask for revision

1/2 page table of ellipses, ghost all ellipses,

1/2 page rough perspective (1 panel), Use the horizon as reference.

Good luck :)
