And this is where I come in. This scenic designer looks like he/she had a lot of potential, but they stuck to the originals and altered them to create their own style. That is not original.
Don't say that the design is 'iconic', because David Rockwell sure didn't have a previous design to copy. He made it his own.
A good designer can reinvent a design. Certain aspects of every show may be iconic, but nothing limits a good scenic designer from creating an entirely new design.
