Welcome. Very nicely done indeed. I really like what you did with the walls, having two arches of walls was a very nice touch and adds depths. Beautiful work all around.
Your set-up begs questions though. What are the dimensions of what appears to be converted fish tank? With two shelves inside the tank, aren't you a tad nervous of the upper shelf "crashing" into the shelf below? I can see some metal bracing in the photos, but still .......
To gain access to the lower shelf, do you need to remove the entire upper shelf display? Or is it hinged in the back?
Again, wonderful work and welcome.
