It’s not the world’s bests street circuit but it’s far from the worst and overtaking should definitely be possible. Looking on Google Earth I’ve picked up a couple of interesting things:
1. There are a number of large carparks along the streets in this area. It’s a pitty they didn’t choose to enter one of them to have a “play” in the open space. Lay down some kerbs and mark out some faster, sweeping corners that street circuits often lack. The run between Turn 10 and 11 is quite narrow, for example, so the carpark on driver’s right could be used somehow I feel. Although it’s possible it will be used as a pit paddock for supports or something.
2. The cars enter a tunnel after turn 7 until just before turn 9. Could be cool.
