hmm, I love woodwind too actually, that's why I use them a lot in the melody part. the other reason is: in this song, which the feeling is slow/ mellow, I think it's better use woodwind. that's why I use woodwind. but I'll try using the brass...
btw, because this is my first time, I'm not really sure about the exact capability, etc. of the real person in the orchestra. that's why perhaps I over-use tremolo in strings section, trumpet register, etc. I really appreciate your opinion about this matter...
and yes, I think this song sounds like a soundtrack...
once again, thanx... :)
