Only people who ever criticized what I was doing was from out of work musicians in the audience who wanted my job! I rarely get that anymore, as most are amazed how good it sounds. They don't know what the arranger is, and most think I'm using "tracks" because that's all they know to do.
On the occasions where I have worked with bands in recent years, they wouldn't know an arranger from a kazoo; they only know I can make the sounds they are used to hearing.
