heyo, you're doing great, perspective can indeed be very tricky, @Kektet reply inspired me to try to explain how i tackled the 4 point assignment.
I'm gonna use the one i did as reference i hope you don't mind, but basically to do these you need to go beyond what the reference shows you, you need to have a understanding of the construction behind what you're seeing, you must think 3d, break it down to simple shapes and, depending of the point of view, these shapes will begin to overlap each other.
and it truly helps to have a reference so you can use it as a base for what you're doing, i used marc's one in my case, keep it up c:
