To flash or not to flash

This evening I went to Valentia Island, to visit a place called Cool  West . These two standing stones were used as entrance portals to a Promontory Fort on a cliff by the sea. I did bring my flashlight and a cable with me to see what kind images I could get. The first and third photo was taken with the flashlight, on the first shot from the top facing down. In the last photo I held the flash from the bottom up to avoid shadows of the stones. I´m not a big fan of flashlight in landscape photography but for a article in a newspaper or magazine I would probably consider it. Let me know what you think.
