Good job for having the patience to draw 250 boxes. My biggest complaint however is that the majority of your boxes have no foreshortening at all. You should be practicing boxes with both shallow and dramatic foreshortening, with more of a lean towards shallow foreshortening. Nearly all of your boxes have perfectly parallel edges. Yes, it can make your boxes sort of look tidy in a way, but in the end, you don't really get to learn much since you miss out on the opportunity to practice drawing boxes with some degree of convergence. On the other hand, you took the easier route by having your vanishing points be off at infinity. When you're aiming to get lines to converge to at an exact vanishing point, it's not going to be easy and you're going to make a ton of mistakes, but those mistakes are what you're going to be constantly analyzing which is what the purpose of the exercise is pretty much all about; learning from your mistakes.
Next Steps:
I would like you to complete 50 more boxes, but some with shallow foreshortening and others with dramatic foreshortening. Don't forget to include both, but try to aim for more shallow foreshortening ones though.
