Perhaps you explained my thoughts better here than I could have 
“feels” real but dimensions changed to focus on functionality maybe
Maybe something we could put in the style guide is an overall information/control density percentage to aim for. Like say 60% as an example. So there should be no more than 40% unused space. Just an idea, no idea what number would be appropriate yet
I quite like this design. Just an idea, maybe the “filename” part could be on the tape or on the tape lid to make it even more vertically compact
