I can definitely see improvement in your work as time goes on. From Super Imposed Lines to rotated boxes you are hitting your ghosted mark closer and closer.
When it comes to perspective and especially when we are free-handing or roughing it, you can try to ghost your line once or twice all the way to the imagined perspective point before ghosting the actual length of the line. Even if we aren't marking the actual point itself, you can imagine where it is!
In the rotated boxes exercise, I think you should focus more on thinking about where each perspective point is in relation to each other. The center box should have vertical and horizontal points to infinity - as you have shown. The boxes next to the center should have perspective points that converge far away - and the boxes farthest from the center have the closest points.
