It's hard to tell from the pictures. The windings look OK to me, just shadow in the pic.
But that doesn't matter to the hall sensor issue. Each sensor signal should toggle as the magnet gaps pass over the sensor. If a sensor is bad, the output doesn't change. If it only toggles sometimes, it would indicate a position problem with respect to the magnets.
