Introduce more depth of focus into the image, through the background completely out of focus to create a greater sense of depth perception.  The image does not show enough distant blurriness to fulfill the illusion.  I agree with JVRenderer, choose a different camera angle to emphasize her small perception of a larger world.  In agreement with the others, the scene is too dark to actually make out any discernable detail.  I can see that this scene is set within a laboratory, but I can't help to notice a draping on the bench.  In terms of real world situations, this is incorrect.  Chemicals can cause fires, and a scientist would never cover a work area with flammable materials. 

The lighting is too static.  Perception relies very heavily on directional lighting; it can create a sense of dramatic depth and mood when placed in the correct positions and aimed in the proper directions.  In addition, there is a lack of purpose in the scene.  There is a fae in a laboratory; what is she doing there?  Is she escaping?  Is she curiously looking around a new environment?  There are a number of suggestive objects within the scene which are trying to tell a story.  It would be interesting to see this developed further.
