Nice melody
The piano could use some extra punchiness in the lower part, it sounds real soft. The drums are quite dominating when they first come in, but when the lead comes in it's better. Enough with that stuff, the tune is really sweet, the beginning is great, although, maybe you could add a string section in there to emphasise the sadness. If the soundfonts you got off suspended-3rd-chord are the ones I got from him, then I think you should try the violin 1 legato sound from the squidfont orchestral sound font.
I think, as a WIP, it's got a lot of promise. The drums could be a great part of the finished song. The lead melody is cool, it has a lot of appeal. I think this song will turn out great once you're finished. You've got a great start, and I'd love to see where you go from here.
Keep it up. =D
