One way to develop more creativity and diversity in your photography is to brain storm beyond the composition you initially had in mind and force yourself to think of different possibilities.
(On a side note, while it is true that many landscape photographers think the times of day near the golden hours of sunrise and sunset are best for dramatic landscape photography, I believe that beautiful photography happens at all times of day and in all types of lighting.)
After I was satisfied that I captured what I was after, I could have packed it up and moved on. But I always try to say to myself, "What's next? Is there a different composition here? Is there a more interesting perspective?" Sometimes, I just walk around and change my location while looking through my viewfinder. Sometimes I change my elevation, (shoot from a higher or lower perspective). Sometimes I change my lens from a wide angle to a macro and look for an intimate view. The possibilities are as big as your imagination.
I have found that when I expand my vision and think of additional possible compositions, often one of those OTHER compositions turns out to be my favorite shot of the day!
