There are three separate proposals in this thread.
1) Change the
regional coat of arms.
2) Change the
regional flag.
3) Change the template for the various
government seals.
Regarding (1), I generally like our coat of arms, though I think it is somewhat too busy, e.g., those laurels always annoyed me and seem out of place. I would not be completely opposed to a conservative retouche should someone take the time to make a serious proposal, but it's also hardly a regional priority. I should also emphasize "conservative": the coat of arms is very strongly associated with our decade-long constitutional tradition, and we should not remove this association by breaking the continuity of the design. Any changes should be minimal, and the new version should be such that it can be immediately related to the old one by someone who sees it without any prior context in mind.
Note that there has already been such a retouche not too long ago, in 2012, when Elu and Gulliver edited Thel's original design. The changes improved the coat of arms, in my opinion anyway, without breaking continuity. Anyone looking at the two designs can tell that one is derived from the other. TRR also did a nice update of their coat of arms sometime last year I believe.
Regarding (2), our flag is fine. The design is simple and effective, and, same as with the coat of arms, strongly associated with core regional values. It should only be updated so as to reflect any changes of the coat of arms (as we did with the 2012 retouche).
Regarding (3), I believe the existing seals leave a lot to be desired. At the very least, the font ought to be changed to something more legible, but I think the whole design ought to be revisited. Unlike the previous two, I don't think there is a need for continuity here. However, any new design should continue to prominently feature the coat of arms, which would make it immediately identifiable as something representing TNP's government.
As a matter of fact, the seal re-design was something I was hoping to tackle during my delegacy. I played around with some concept designs very early on, a little after the Executive Staff array of badges were created. However, I never found the time to complete this project.
