A background would look nice, to hide the things behind the tank. Solid color backgrounds give a little depth to the tank.
IMO, bright substrate and bright decor steer the attention away from beautiful fish. Also, bright substrate may stress the fish, especially if it is white, since they reflect the light. I had white substrate when I had my clown loaches, but found them to hide allot. When I switched over to dark substrate, they soon started being more active in the tank.
