I hate to be the bearer of bad news, but you unfortunately seem to have misunderstood what the "contact point" lines are for each ellipse. It appears that you drew lines passing through one contact point for each ellipse, resulting in lines that run along the length of the cylinder. That's not what's depicted here or demonstrated in the video.

Instead, as shown here on one of your box-cylinders, the lines we are to draw here connect the pairs of contact points for a single ellipse at a time. Thus, each ellipse has 3 lines of its own, one converging towards each of the box's vanishing points.

I know you tried hard for this one, but perhaps in your eagerness to complete the revisions correctly, you still may not have checked the instructions closely enough. I'm not going to reassign the same quantity of revisions from before, but we are still going to need to make sure you can apply the approach correctly - so let's do another 10.
