When the horizon is tipped our brain keeps trying to put it back to normal unless.......... the subject fits with whats going on. This is a rule to break on a regular basis. Tilt your camera, experiment with the direction of the horizon.
While you experiment with your camera keep some of these guidelines in mind:
-Try turning your camera every direction once
-Look at your finished photographs to understand what worked and what didn't
-Make a subject using the tilt of the camera
-Use the tilt to show the subject from the very bottom to the top
-Once you've tested this ideas, experiment MORE
Go try it for your self and share your best shots with this photography community!
