sadness and such

The far left is frustration. The grey left is sadness. The middle is I'm not sure, maybe repressed emotion. The grey right is serenity. The far right is winning a prize.

Sadness and serenity are smooth, and don't overwhelm me. They are also oddly similar, like accomplishing something, and feeling good about it, but feeling sad that the journey is over.
