Through the travels of photography you learn different elements of what makes a picture good or great. For me I'm leaning towards body language and the engagement of the eyes. Those two things can say a lot about a person or a picture. The body language shows whether you really want to be there or you're just going through the motions; and the eyes (with the right connection) can almost make you feel that you are there-wherever there is. Always get the body language (pose) the way you want it and get that connection with the eyes through conversational confidence builders. I'm telling you it will do wonders.
