Wow Nate, That looks Fantastic.
Great Segmentation, and Centering.
I love the Continuity either side of the Centre Band.
As regards to adding Metal in between the segments for your next one.
If you were going to use the same colours as this one, I would hesitate, as I believe that the Orange, Black and White, are bold enough and instantly grab your attention.
I don't know if the adding of a silver or brass insert either side of the White Centre Segment, would do much to add to the Blank. If the Center Segment was a Dark colour or Black, It could then be an advantage.
That is just my opinion.
But it isn't going to cost you much to try it, if it doesn't work you have only lost a Blank, and Tube.
Great work,
Brian.
