You'll get a lot more responses if you post this in the Songs Forum, further down the page.

Just for your information:
The Songs-forum is for this kind of posts, and it's quite active in giving comments on the artistic works of forum members. It's also quite fruitfull to compare your work to that of others and to hear what SONAR is capable of.

I think you did an excellent job.  This is a good arrangement and a well-done mix.  I would like to know what you used for the strings because the sound is excellent and well suited to the track.  (I have both Vienna and Hollywod but sometimes have trouble getting simple lines to integrate into a light mix.) 
The pianos fit well into the arrangement.  I am usually not a fan of layered acoustic and electric pianos and normally prefer acoustic only, but in this case you blended them perfectly and I really like the way they sounded together.  Nice touch.

I enjoyed the drum sounds and the kick drum in particular is nice and solid without being too aggressive.

As far as suggestions go: I felt the vocal was a tiny bit loud compared to the track when it first entered, but 1-that is entirely a matter of style and 2-it is MUCH better to have too much vocal than not enough.  I personally would probably either bring the track up a little more before the vocal comes in, or else use a master bus compressor to smooth out the level.  Again, that is all a matter of opinion and it certainly works as it is.

Congratulations on a good production.  I look forward to hearing more.
