There are many ways to achieve Visual Tension. For example, something that feels it is holding too much weight and should snap or break at any moment. It could be an object that is precariously situated so that a slight breeze would cause it to go tumbling. Consider asking Mr. Google for options too. Those are just suggestions... create that tension for the viewer (even if it's a photo magic trick).
