Nothing is 100% original or unique, but it's the artists' vision that creates new and exciting works of art. Stop worrying so much about originality as you're only going to get frustrated with what you're doing. Instead create art that shows your vision and your perspective of the world. Take concepts that have been used over and over again and put your own personal spin on it. You'll find that to be a more rewarding experience then fretting over finding the perfect unique idea.
