Pretty laid back and happy, from what I can tell. Some chromatic non-harmonic tones going on, same melody throughout, and it's relatively cohesive. My only complaint is that the piano synth sounds... too synth-y? Maybe it's just not my taste. Anyway, I liked it. Nice job!
Pardon the music theory jargon by the way; I'm a music theory major, so analyzing music is practically automatic, aha. You might want to check out some typical composing conventions for smoother voice leading (of course, rules are meant to be broken) and chord progression for future works. They can improve your writing ability tremendously.
Anyway, good listen. I enjoyed it. :)
