The Mysterious Arcs in the Sky

This is in response to photography 101, day 10 assignment – Mystery.

It was at one night of Downtown Toronto.  The weather was overcast, indicative of upcoming thunderstorm.  While aiming my camera towards the sky, I used long exposure to create a effect of the circular arcs.

Do those purple arcs look like the lightening emitted from heaven through the darkness of the night?

For me they were just like the eyes of a mysterious creature to look over the people on the earth.

What do you think?
