Visualizing song structure to maximize studio productivity

My band is preparing to record our first full-length album, and I decided it would be helpful to prepare visualizations of our (complex) song structures for the producers to accompany our demo tape. My goal is to help the producers become familiar with our material as quickly as possible, while also spotting problem areas (“there are no drums here, so we’ll need a click”), and providing a reference during mixing.

I whipped up a design for this and am looking for two things:

INPUT ON THE DESIGN

How is it? Can anyone recommend ways to improve it? Please keep in mind that I am on a very tight timeframe — so anything highly elaborate is out.

REFERENCES TO SIMILAR WORK

Has this been done elsewhere? I would love to see other visualizations of song structure for this purpose.

Any input is greatly appreciated.

Thanks,

Ryan
