Stained glass window bangle

I have been trying a different style in my color anodized aluminum today - looking for a more painterly effect.  My subject was a stained glass window:

So this is just a work in progress, trying a new technique and seeing how it works, what I need to change, etc, etc.

I was hoping for more vibrancy in the colors but I guess painting them on leaves them paler. Maybe I need to use more concentrated colors for a painterly effect?  Or maybe I need to try this not on a matt finish aluminum, but on polished aluminum...

Hmmm. I like the idea.... it encourages me to keep going with it.... What do you think? Soooo many possibilities!!!
