Sacred Piece: Amen

Here is a short sacred piece titled "Amen" which I may keep as a solo sacred piece or add to my Requiem Mass, "Missa Requiem in A Minor". It is very short of course, and one should imagine it right after the host has been turned into the Body of Christ during the Mass. I meant it to convey glory. How is it? Too short? Do I need to layer the voices better? Does it fall off in the middle--the beggining and end seem to be strongest to me

amen1.mid

Without thinking too much about what I am going to write here, to me it comes over as quite serene, but at the same time, I feel it is more melancholic than glorious... Maybe it's the key that it is written in...

Cheers,

Serge
