Very good! Beautiful music!
Is this your own composition, or an arrangement of another piece?
Just be aware of the F# in your harp part, it's in the middle of a two of F's (One F in beginning of measure 1 and one in the beginning of measure 4). I hope you know how to write harp parts and taking pedaling into consideration?
Since the tempo is quite slow, it might be possible to pull off that pedal change (especially the last one, which must be executed in the middle of measure 3, in time for the F's in measure 4, but after the sound of the F# is dampened). Ask a harpist if it is playable, and if it will sound good (The F# may need to be dampened artificially before the pedal change).
Or you could just take out the F# and replace it with a diatonic tone. Remember, concert harps are diatonic! ;-)
Those fast runs are also quite virtuose, if that's not what you want them to be, you could have replaced them with pure harp glissandos?
I would say you should give the flutes a rest in measure 23. The low flute register would be heard very well, and it just makes the jump to the high F more difficult. I would have put it in the clarinet parts.
Exciting from measure 58! I would like to hear more of that. :-)
Good job!
