Dude, sweet. I hope you can load a sound file. I would love to hear them. I love the colors. Does it matter if you tune them? Who knows what they should sound like. They sound like they sound. That's cool enough.
Aah ..... but not if they're to be played along with other instruments! And/or for conventionally notated music.
Number 5 is my favourite - as Lee says - personal taste.
Most native American flutes will never be played with concert instruments. But most are played in flute circles. So the flutes have sound good together.
