All the bridging at the bottom and even the single bridging at the top contribute nothing to the structure. The four vertical scabs inside the corners are also superfluous. I would erase them all from the drawing.
The connecting trim from the stand up to the canopy is an interesting idea, but one that would be hard to bring off sucessfully since it blocks some of the view of the tank. Now if it were at the back, and actually supported the canopy while creating a background behind the tank with optional space for a diorama, it might be easier to justify.
Canopies are a lot easier if you install wiring and fixtures for power compact twist bulbs and produce a more versatile lighting array since you can change the bulbs for different wattages and spectrums fast and the lights don't block access to the tank nearly as much as long tube lights and their fixtures.
