Good stuff.
The imagery I got from this song was PRICELESS. The chopped up melody was calming, yet as you stated, also exciting. The strings in the background served only to amplify this feeling. As a result I had some messed up images happening, I loved them all.
If your going to use the strings, I say why not expand on that. Perhaps introduce a small piano riff, or perhaps a booming iron bell when the melody suddenly jumps, and then after a slight riff, goes back to the original melody.
Good stuff.
5/5, keep them coming or die.
