How to be constructive with this...

I will say this, there is nothing I can think of that can "Fix it" or "Improve it" to a point where it's very much different i can feel and nearly see what you were aiming for. I can see the little village in the snow globe, as they are doing their little things, but I think the problem is there is no climax, no resolution that's different from the beginning which is why I think people been giving it a low voting score.. but it sounds nice as it is, and by climax or resolution, perhaps you could make it a tragic where you give the visualizations of the snow globe falling, the song would speed up, and upon the crash it would make the notes all louder and there would be silence for a while while we can hear softly in the background the music box sound playing away till it comes to a slow end.

There isn't much you can do with a snow globe in music that isn't tragic. At least I cannot think of anything else that would help give it climax, at this time, with what you got so far. A happy ending would have no resolution since it already starts happy.

Hope this helps.
