Just a little more contrast to the background wall and the electrical supply box. The effect of this box on the composition, I feel, is to arrest the eye and direct it to the central focus of the painting. I have done the first session on the glass in front of the girl. When painting glass, I focus on the distorted shapes of the background that can be seen through it. Then, after some refinement, I will add the highlights and light reflections which should, I hope, have the effect of making it look like the material that it is made from - glass.
