I really like this idea, the waves, sand and motel look great. For me the clouds in the distance look overdone. (don't know if this is caused by the black and white conversion or tweeking during processing) I feel this would have been stronger for me with a tighter crop from the left.
To answer the question posed in the title: keep going until you find something interesting to photograph. (Ouch, sorry about that, but the title was begging for it and that snarky comment would not stay in.)
