I'm swapping in here for Tofu, as we believe there may be some miscommunication here. The issue we're specifically trying to get you to avoid is specifically drawing your boxes in a 2 point perspective orientation, which tends to happen when we don't adhere to a Y shape for our original Y. We can see this in your boxes in number 1, 5, 6, 7, 9, and 10.
While you certainly can use the Y method in this manner, for this set we want you to start out with a Y in the manner shown in the video for this challenge so that you are forced to use 3 point perspective and consider how all three sets of edges are converging in a consistent manner.
If you are still unsure of what I'm asking, feel free to ask for clarification on specific points, but I would like you to try the 10 again, being sure to avoid the 2 point perspective and sticking to starting your use of the Y method with three edges arranged in a usual "Y" shape.
