Hey there! The main issue I see here is that you’re not establishing a horizon line, and because of that, the lines aren’t converging properly toward the vanishing points located on the horizon line. First of all, establish the horizon line. Once you do this, you’ll know whether objects are above or below it, and therefore whether we should see their bottom or top planes. Having a clear horizon line will also help you make the lines converge more accurately, not necessarily perfectly, but definitely more precisely. :) Also, keep in mind that objects have volume. For example, the cylindrical towers look flat because you’re not considering their three-dimensional form. Hope this helps!
