Hello there! When rotating boxes while using the same horizon line, keep in mind that the angles of the boxes should maintain their 90° relationships. This helps prevent the lines from converging incorrectly and makes sure the perspective of the box doesn't look strange. Obviously, you also need to make sure that the lines converge toward the appropriate vanishing points along the horizon line. Speaking of vanishing points, notice that when you rotate a box, the vanishing points move along the horizon line. Keeping this in mind will give you a better understanding of how to rotate boxes in perspective. :) Hope this helps! | Artwod Feedback
