Miandza teaches you how to draw a complex room. You will start with two rectangles, one smaller than the other. Also draw 3 perspective lines - one horizontal and two diagonal, meeting in the middle. After that, start creating objects and pieces of furniture. Also add walls, doors and windows, according to the perspective lines. Use a darker pencil when you're sure of the things you are drawing. Now you start working on details. Don't forget about the floor and ceiling and add details and objects to those as well. You can also add color to walls and pieces of furniture to give it a more realistic look.
