Hmm...
Um... Sorry to break you bubble, but I don't think this is actually a competition. It's more of a casual challenge to see what Newgrounds audio artists can do.
I think this is pretty good. Honestly, I don't exactly hear the melody of this song, but the chord progression is there. Still, I think the choice of instruments is pretty decent. I like the violin in the backgrounds.
Mixing can be improved a bit. Seems like this song lacks in high frequencies. Adding some higher frequency instruments may help a bit. Some instruments also seem a bit muffled.
This song is great. I like the overall progression of this song too.
