Is that... love? The speech/thought bubble seems to clash with the melancholy motive, if the black's meant to mean a lack of, maybe something like a shattered bubble, or a cross, or the heart in two pieces would get that across better? Everything else about it is beautiful. The sun. The girl. That cats. A sad but serene scene, somber yet spirited, and theme maybe referring to the bridge over troubled water? Really nice piece.
