Good dance
I think the second half of the dance can be better described as follows
B1
Balance circle of 4  (4)
Petronella  finish taking left hands in a wavy line of 2 with person you swung. (4)
   (Tell dancers to think of their group of 8 as a racetrack or paper clip of 8
     everyone facing CCW)
Balance the line of 2 (4)
Walk forward 2 places in the racetrack,  looping left at the ends, take  left hands  with
shadow (4)
B2
Balance with shadow (4)
Walk forward 2 places in racetrack
Those in front of their partner turn back over right shoulder to swing partner,
