Harp Thing Song Thing

I'm not sure what to do or how to go on, I'm just free writing so if think adding an instrument or something like that I can try it.

I think you've done a pretty good job with the harp. I can somewhat tell that it was "free-writing" in some of the places where you had counterpoint between several woodwind voices. Their combination sounded a little awkward to me, so I would recommend taking a second look at those melodies and maybe doing a little bit more planning as to how they all fit together. Otherwise, you've got a pretty good thing going.

Largely agree with fishyfry. There are some spots that crossed voices affect the writing as well as the old writer's trap of "having everything do something". Sometime's that's just not important. 
It builds slowly, so why not go further with that with the percussion and brass sections. It also lets the counterpoint be divided by section which is a cool effect.
Cheers!
