AS it picks up at around :54 I find it a very happy and beautiful composition. I quite honestly yearn for this kind of grasp on melodic parts and harmony. The harp part is beautiful, and I'm jealous outright of it. The arrangement of this piece is solid, but the ending is undoubtedly as you stated. As well, the entire piece is fairly dissonant, so even though I can tell the mood is happiness, the sounds just kind of clash. Of course, that's just how I feel about dissonance at all, so feel free to ignore that last critique.
