You did wonderfully at achieving convergence of the boxes. You developed one bad habit over the course of the challenge though which is to put all of the vanishing points extremely close to boxes. This makes it easier to have accurate convergence but it makes the perspective so extreme that it undermines the illusion of space. In real life one would basically never ever see a shape that looked like that (e.g., upper right corner on the image of the page marked 162--that's a salient example, but it's a trend through all your boxes especially in the later 150 or so).
Anyway, good job. Your lines are very straight and you are developing a good eye.
