Exhilaration? Fear? Abandon?
It matters not, there is no deciding to go back, no ending up on the pier again without hitting the water first. Every swim starts from a moment like this, perhaps less dramatic. It is a miniscule (or major) act of courage just to start. The draw must be pretty powerful.
Clean up notes: I see this as complete the way it is... but to make it fit with the other pieces in the group, I would play with adding some teal.
