One thing I would change on his design is the use of massive mirrors to collect sunlight and the large windows to let it into the station. I never liked the idea of opening up a large section of a space habitat for radiation to enter in from. It's better to pump in sunlight via fiber optic cable. The solar collectors would be far smaller than the massive mirrors proposed.

As for food production, aquaculture is a great way to produce protein for the citizens. Some systems can accommodate several dozen fish per cubic meter. Several 5,000-10,000 gallon size tanks would easliy supply all the fish needed for a population of 10,000-20,000 people.
