Converging to a singularity

hi busker i enjoyed this one. not sure both similes work well together. a suggestion would be to have the 4th line as [to a close] and remove [like a curtain]

Converging to a singularity

The red bus climbs 
uphill, and is gone –
drawing the stillness 
to close,  like a curtain,
like ripples returning
on a pool’s surface
from a stone dropped in water:
the wave that was coming
to the centre returning,
the sound of the engine
made silent again.
