Good Start...

I like the whole concept. First off, get rid of the limiter. ;-)

As for the piano, you should vary it more. It is too prevalent on the downbeat. It really beats you over the head after a while musically. Add some syncopation in the piano to help alleviate that constant pulse on the downbeat.

The strings are interesting. I'm not sure I like their sound. I'm not sure what it is, but they don't mesh well with the piano. You should try using a different type of strings there. Or at least tweak the settings on what you have.

Add some reverb to the piano. It doesn't sound like there is any at all. Something rich in color would be appropriate.

You should add some panning effects to the strings if you are keeping them the way they are. I think they would sound better if they were wafting around and through the melody line. Rather than just sitting idle and taking up space.

This is a good start though. Definitely let me know when it is finished.

2/5 and 4/10 overall, for now that is. ;-)
