Creating a great looking scene is both fun and challenging, it takes lots of little touches which tell a little story of what is actually happening as the photo was taken so to speak. Trying to visual the scene in advance is really important, what is the little story that is going on in this scene, a discussion about where a box is going to be placed or someone watching another person working. Have a look at a similar scene in real life, examine all the little details that go make it a real scene. Composing a scale scene to be as real looking, requires trying to get as many of the details into your scene as you can.
