Hey! Well, if you're having trouble drawing boxes, the first thing I'd recommend is avoiding curved grids. They tend to make accurate convergence much harder to establish. Instead, you could draw a grid using a ruler, just to make sure your vanishing lines are properly laid out. On top of that, regardless of how many vanishing points you're using, you need to make sure that the parallel edges of your boxes converge toward the appropriate vanishing points. It doesn't have to be mathematically perfect, but the convergence should be more precise. Keep in mind that the lines should converge toward vanishing points located on the horizon line (assuming you're working with one-point or two-point perspective). If a box is above the horizon line, you'll be able to see its bottom plane. Conversely, if the box is below the horizon line, you'll see its top plane. Hope this helps! | Artwod Feedback
