Can I just add some constructive criticism?
The stand should, IMHO, some diagonal bracing across the back and sides to prevent it folding over in an earthquake or someone leaning on it. I know you have glued and screwed it, but with the weight on top, it could still let go.
This can be achieved at the back and sides with a sheet of timber, ply etc, or some metal strapping as used in the building trade. Painted black of course.
I really like the idea of the exposed timbers theme you have done too so think the metal strapping would be your best option.
