Hi there, so unfortunately these are still facing the same issue where you're trying to keep your lines pretty much parallel.
It's a bit difficult to explain the process more than the exercise and my critique already have without just going in circles but I do have an idea we can try that may help.
I'd like you to draw 10 more boxes but for the first 5 I want you to place your vanishing points on the page, doing so will hopefully allow you to get a feel for how your lines should be converging. After you complete these boxes with drawn vanishing points you'll finish the next with as you would in this challenge, without drawing vanishing points but instead having an idea of where you want them to be placed in your mind.
Before you get started if you have any specific questions that can help clarify the process or help you understand what you're trying to do, please ask them. It'll not only prevent you tackling these boxes blindly but also save both of us time and from grinding.
Currently it's difficult to give you any resources or advice because all I know is that you don't understand how to do it, but can't be certain which aspect is leading to that confusion.
Next Steps:
Ask any questions you have that will allow me to help you more.
Draw 5 boxes with predetermined vanishing points, and then 5 boxes without vanishing points being drawn on the page.
