Lines:

In your ghosted lines and planes exercise, there is a slight bit of wobble in some of your lines. Take as much time as you need to ghost your lines and prioritize a smooth mark over an accurate mark.

Ellipses:

Mostly alright, but in parts of the funnels exercise the minor axis doesn't cut through the midpoint of all the ellipses in each funnel, try to remember that the minor axis should bisect he ellipse and half each one.

Boxes:

Some of the placements of the faces of your rotated boxes are a bit off, and in organic perspective lineweight should only be added to the parts that overlap, not the whole overlapping boxes.

Everything else is fine! Good luck with the next step!
