Oh, my love has gone, Carried away by the see, But, no matter how long, That I have to wait, I swear to always wait for thee... In the second line, see should be sea and there should be no comma after long in the third line.

He placed his hand on her elbow, a gesture of comfort, but she continued to ignore him, her eyes ever vigilant in their surveillance of the oceanscape before her. It seems to me like you are a little comma happy, but that might just be you style of writing. I personally would break up this sentence and a few others I read, just so it doesn't seem to ramble. But, like I said, this is a personal choice!

I also would make new paragraphs every time you start dialogue. It's more pleasant to the eye and is easier to read.

Other than that I thought it was very good! A nice rough draft! Maybe go back and add more details? Make it longer? Describe the lover, what he looks like, what the departure had been like (just a little bit more!). Describe the scenery more, paint a picture instead of telling us she stood on a cliff.
