As far as a technical aspect goes, much better! I can see the converging lines tell where the vanishing points are. There will be a section in one of the perspective videos about how to measure the foreshortening of boxes by finding a mid point and drawing diagonals.
I am not sure if I mentioned it before, but I do adore the sketchy and whimsical look of those first images, very fun, very alive, a joy to look at. They just aren't technical exercises which is what a lot of the early lessons are about.
Its looking good, keep at it!
