This piece matches sonically with the artwork. It has some nice harmonies and melodies-- a very light-hearted work. The only thing I didn't like too much was the string sounds, although, it did supplement the piano nicely with it's own arrangement. One thing I would like to suggest to you next time is to try part-writing the strings. Split the notes of the chords up within the different string sections unless of course you're going for a pad sound which is fine.
When I listen to it, I certainly hear myself in the bright sun amid an open field.
