Some tips that you can try:
1. Move in closer to your subject.
Rely on your feet instead of your lenses to get up-close to what you are shooting. Getting in close eliminates unwanted background distractions, and in the case of portraits, the interaction makes for a more engaging photograph.
2. Be aware of your light.
Light is what you depend on for your beautiful pictures, so be aware of the light you have around you when you are shooting. Different types of light can create different interesting effects.
