One needs to be very alert as the Sunrise and sunset happens pretty fast ie. we get only a few seconds to get the Sun with the right light.

A lower ISO ie. ISO 100 or ISO 200 should have been fine. And if there would have been a few birds in the foreground or sky, then it would have been even better. There seems to be a dust spot on your sensor. Thanks for sharing.
