Alright! ill try to make it reflect.
My quick example: 3196446
Blender artist here! Light should be reflecting off of the front/sides of the cube. The light from the light source isnt all hitting that one face then going twords the camera, its being spread around. Obviously depends on the material though. Still, there should be some minor light reflection off the cube onto the floor.
I can look at the mona lisa but i cant make an exact replica just by looking at it
mmh maybe add some ambient occlusion under the cube
TOP OF CUBE IS DARK, MAKE IT BRIGHT
cool save, also it looks like its on space due to top face not being very illuminated +1
