Composition rules that should be followed no matter what
1. Make sure the entire frame is full, don't leave empty space
2. Keep your entire subject inside the frame, don't sever limbs off your subject
3. Keep your image centered when necessary
4. Make the most out of shadows and lines, if your subject has texture, use it.
5. Blur the background, when your image has a subject and a background use blur to the max.
6.Your background can be interesting too, sometimes the background is just as good as the subject.
7.Use symmetry to your advantage.
8.Use depth to your advantage, creating a sense of depth in your photos can make them seem more realistic.
