I am also trying to improve my box rotation skills the last few days. So I did some research, which might help you as well.
Here is a great youtube video, which shows how the vanishing points change when you rotate a box (https://www.youtube.com/watch?v=rkp1xfWJ9n4)
Also what really helps is looking at some cube (box) in real life and turning it (You can build one yourself with paper, if you have no box available\^\^). And then try to draw the box in different rotations while using the real box as reference.
And some other thing I realized today: When you rotate a box the vanishing points are changing (at least two vanishing points are changing and most of the time all three). This is in contrast to when you only move a box, then the vanishing points stay the same!
I did a picture today to help me see the differences, maybe it helps your understanding, too:

Good idea, now I want to make such a tool, too. :-)
