I almost thought it was a real orchestra until the strings came in! But that was mainly because it sounded a little dampened like might happen with a live recording. So i think the synths were a little lacking, the drums were nice but the strings had too fast and smooth an attack. I'm not sure what software you're using or if it'd be possible but varying the speed of the instruments attack at different parts could help make it sound more natural.
However i think the main element of this piece is the composition. Which i really liked! Lot's of interesting melodies that really captured an "Aladdin" feel. I liked the variation of monophony and polyphony and the chords that sort of broke off into melodies. I loved the part at 0:58 with the wind instrument and the metallic sounding percussion, very magical and enigmatic.
So all in all i really did enjoy the piece though i felt it was rather let down on the technical side by dodgey synths and bad mixing.
