That water definitely gave me a cool chilled out feel, good on you for that! This track is really rad sounding, and seemed like it was ready to explode into some crazy drop that never materialized. You should extend.
I love the detail that you've put into this, without making it too overwhelming (for me, anyway). It's exactly the kind of thing I enjoy listening to, because you never know what's coming up :)
What it needs now is some chordal variation, some development of the theme, some larger structure, and to me that would make a fantastic track!
