The scene but not of a loving story

As you know, in Drama we are working with a play called "Journey's end" . So to start with the play, we read a scene.  We have to read about  how the dug- out were, especifically in British trenches.

After readind the scene, we have to draw how we imagine that the dug- out was; obviously we have to imagine according to what the book said. Here is my drawing.
