Lines:

1) In both ghosted lines and ghosted planes, your lines sometimes have a bit of curvarture to them. This could be because you are struggling with using your shoulder to draw. Another reason could be that you're concerned about accuracy, in which case make sure to prioritize a clear smooth mark. That said as the majority of your lines are good, I think you will not have much trouble developing these skills.

2) For some edges in planes and some in the ghosted lines, your lines are missing both points. Be sure to rest your pencil on the starting point for a second before you draw your line (provided that you have throroughly ghosted).

Ellipses:

1) Main thing I can notice is that you don't seem to be that confident in your ellipses. Take as long as you need to ghost so that you don't try to compensate for any inaccuracies in your second mark through. As stated above, prioritize confident, smooth marks.

2) In ghosted planes and in your table, the ellipses either undershoot or overshoot the bounds by a wide margin. Try drawing tighter ellipses and putting more forethought into the ellipse. Also the ellipses in your table overlap quite often when ideally they would only form tangents to each other, just touching. As mentioned before, tighter ellipses, more ghosting and forethought would probably help.

3) In funnels, the minor axis is supposed to cut through each ellipse into 2 symmetrical halves. Just keep this in mind when drawing not just the ellipses but also the funnel.

Boxes:

1) In rough perspective, your lines seem to have struggled a bit more, but this ok just try to ghost more. However some of the horizontal lines on the front facing plane of the boxes aren't parallel with the horizon line. Just try to rectify this in future attempts.

Other than that, it's all fine and up to standard
