None of the models were square or blocky. The very initial models were, but none were included in Version 1.
All of the updates since November/October time are what will be included in the second version of the mod, which has very similar functionality to that of the Los Angeles Mod, with a British spin on it, such as Terrafix and Genisys command icons, and ambulance standby points rather than one massive hub, varying grades of fire and ambulance staff with appropriate tabards and other clothing.
It's unlikely the Mod will be released soon, as I am busy with University, however, nearly everything is done, all unit icons are now done, making the mod much easier to use. Also, no one else is currently working on the mod.
