Always remember that when you take a picture, keep in mind the feeling of satisfaction for every composition you make. If you feel that something is lacking, then there probably is.
You don’t need to create a very exaggerated shot. Like you must have everything in your framing.
For me, few is plenty… if you have so much subject in one shot then it will be hard to see what your main subject is and in the end it will be difficult to see the meaning of your photograph..
