Lines are p confident and neat in general, good job! Only issue is you're repeating somel lines. No matter how off a line is, don't repeat it, keep going as if it was correct. You also aren't drawing starting and ending dots on each line you draw. On the ghosted planes for example, there are some lines where you didn't place it. Be careful with that, as it's pretty important to apply the ghosting method.

Ellipses are p confident too again, good job overall.

On boxes, overall a good job too, but you're repeating a lot more lines. Remember, never repeat a line no matter how off it is.

On rotated boxes, some of your boxes weren't actually rotating, careful with that, this mistake is explained here.

Don't forget to draw through your boxes on organic perspective. You should be able to see the boxes, even if they're covered by other boxes. You can add lineweight to clarify their relationship on the line overlaps after.

I recommend trying more overlaps as well. You can clarify after the overlaps by adding a confident, drawn with the shoulder superimposed line on the part of the silhouette of the boxes that overlap. Perspective on them has issues but you'll work on it on the box challenge, so don't worry about it!
