Sunsets are always beautiful but often clichéd.
Creating a sunset image which is different is really about just seeing differently. Looking for the relationships between horizon, foreground and the setting sun. Seeing an unusual combination come together perhaps only for a brief moment as the sun rapidly descends though the scene.
Finally there is luck. Just being at the right place at the right moment when the backlight is perfect.
