Starting with the first 50 of your revisions, you've handled these quite well. For the most part you're focusing on how your lines are meant to converge - there are a few small hiccups, like in number 2 where you've got one of your blue edges going way off from its intended vanishing point (suggesting you lost focus), but that being early in the set is much, much less of a concern.

When you move onto the second half of the set, one impression I'm getting is that you may be intending to keep your sets of edges parallel on the page itself (rather than having them converge towards a far off point, which would still result in some convergence). As you progress through the set, I feel that your intent here shifts more towards pushing and exaggerating the convergence a little more, which is more in line with the instructions (which for this particular issue you can review here in these reminders, specifically the first bullet point).

I'm going to mark this challenge as complete, but do be sure to keep in mind that our vanishing points are only ever forced to infinity (resulting in fully parallel lines on the page) when the set of edges runs perpendicularly to the viewer's angle of sight, which given the random rotation of our boxes here is not something you can rely on for this challenge.
