Very good!
I disagree with TerraNation. His review looks like he wrote it while he was drunk or something. Doesn't need sidechaining done to it, it's fine as it is. Very professional! Also it doesn't matter what samples you use, as long as it sounds like it fits in, anyone who knows nothing about FL studio wouldn't even notice it. Even people who do use it don't mind it (E.I. Me)
I say if you use FL strings, and it fits right into your song, go for it. Who the crap cares if the instruments been heard before? It's like if some random dude criticized Eric Claptons songs because they all had Acoustic Guitar in it. What gives? It's music, listen to it and enjoy it.
Pads were super sexy, melody was epic, build up was epic, overall tune was epic. Nuff said.......
