Check your lighting
Lighting plays an important role in any photo, because this makes the picture more dramatic. Always make sure that you play around with your camera settings to get the right lighting.
Sometimes, the only way for you to get better, is to practice shooting everyday. The best way for you to practice is to take as much photos of you can of everything that you take an interest in.
Experiment with different angles
This is another great way to make a photo more dramatic. There are some photogprahers out there who do not give credit to how the angle of the camera is placed when the take pictures, they just point and snap.
