Hey there Raen!
The song is pretty good except a few things. That background note plucking (guitar?) has a few notes that seem to clash with the trumpets when the note plucking sequence begins to go up in pitch.. can't explain it any better than that. It could just be my sound card, but there are a few other parts where there is clashing, like that high note with the strings. Most of the song is great though.
Also, I started to work on converting it in FL Studio, but I was just trying for a quick conversion, replacing midi with wav samples, but I couldn't quite place where the clashing was and I've given up for the moment. I'd need to listen to the original and compare them to see what's bothering me about it.
I especially like the part 0:47 - 1:01. As far as I can tell, that sounds perfect.
