Take the time to explore and play with your post processing, as well as your capturing techniques for that matter. Don't be afraid, or self-conscious. No one has to see your efforts if you don't want them to. But you may find that it will stretch your mind creatively and inspire new thoughts about how to approach your subjects. Push yourself too far, then come back. Try new directions. You'll know when to stop, then realize it wasn't time and keep going. Have fun and play with the possibilities.
