Artist's insight needed please!?

If it was me, I'd do something abstract and use color instead of black and white. Color does a much better job of giving you a feeling or emotion. How did you feel when that moment happened?

Colors:
Bright colors do a good job expressing happiness and excitement. If you want it to be happy and calming instead you can add some white to your bright colors so they're softer and less intense.

Shapes:
Large curved lines and rounded shapes express calmness, especially if they're mainly horizontal. (it reminds your brain of a horizon, or looking at the ocean or sunset)
Small repetitive curved lines or rounded shapes make you feel more excited or like you're listening to something with a good beat.
