I was expecting something slow and dreamy but instead you opened with what can only be described as a pirate type theme.
The sounds are decent, but sound a bit too MIDI for me and un-natural. Which is to be expected if you're solely using FL Studio.
Musically, a bit thin and dry. Nothing that stands out to me. Not quite sure how to describe it. A think you should try deep bare fifths in some low string section and perhaps fuller chords in the high strings? You could even do octaves in a Double Bass section or something. Just fill it our a bit,
The synthesized bass was a pleasant surprise though.
Overall, not bad at all. Looking forward to your next piece!
