A couple of thoughts:

1. The broader white on the green/brown ground will dominate the sett from a distance in much the same way that it does on the Forbes/Lamont sett or the yellow does in the Gordon. If that's not what you want then think again.

2. I don't like the blue shade which I find too insipid and it it were me I'd make it darker.

3. The green stripes on the blue are too similar in shade and will disappear when viewed at a distance, so what's the point of having them? Similarly, the white on the blue will look very faint unless it it is balanced proportionally against the white on the green.
