It sure sounds like a competition henni which is probably why no one wants to contribute .
I listened to your version of how great is our God . There is something wrong going on with the timing of the chord changes as they seem to be lagging behind the melody . In fact there is just too much going on in the song generally . If you have to use the trumpet as a lead voice then playing that lead voice as a chord diminishes the Beauty of that lead sound . I respect what you are trying to do and I know that you love what you do . Sometimes less is more especially when it comes to using your arranger . God bless . worth
