Pretty good.
Just a few suggestions:
Harmony. Sometimes having quite a few instruments on one melody can sound good, but here it gets a little tiring, for lack of a better word. Adding little differences between the violin section and flute/piccolo thing (whatever it is, you get the picture i think.)
Percussion. A good percussion section would do wonders here. Not to say it needs a constant beat going, simply a cymbal crash at the beginning of every other measure or so, and then a light drum roll about a half note later would sound good.
Keep up the good work.
Now for the review.
Originality: Completely original as far as I can see. Sounds a bit like the Star Wars theme or something for a second there. Haha. 10.
Diversity: Repetitive, yet only moderately, so it's ok. 9.
Clarity: The flute/piccolo thing sounds a little wierd on the lower notes. Maybe try transposing that back an octave up. Otherwise, everything else is good. 9
Effort: Not only good effort, but good results as well. 10.
