@laura-yong Draw a bounding box around your more complex objects to see it as a basic form. That will help you see how the perspective of the object should be. Also it looks like the majority of your buildings are parallel so that means they should each go to the same v.p but at the moment they dont, some go to the center whereas others go more to the right or left. Use the line tool and extend all the lines you have already drawn to see where there v.p's are and it will help you fix them
