Okay, you wanted my input in the stream, so lets see if I can be useful.
(Sorry to leave suddenly...Gun control is deeply offensive to me as a subject.)


If I understand correctly, you are looking for Napoleonic influence for the uniform?

This may be useful-
It looks like you're using the habit-long for a basic inspiration. (Scroll down the page.)

This style of basic uniform coat has long tails in back that are not very visible from the front because of the severe turnbacks.
(I have a pile of photographic books on these uniforms. Pics taken at mainland European Napoleonic events with re-enactors who spent decades getting their kit perfect.)

The sash under the waistcoat/vest is a bit odd..If a sash was worn, it was normally worn over the vest.
(It would be uncomfortable as is...I've worn them.)

The tight breeches and boots are more like Regency period; 1820s immediately after the end of the Napoleonic wars- But there were troops who did wear similar things during the wars, so its not out of place.
They just became more common fashion during the regency is all.

The eagle sleeve distinctions and pturgas, (Shoulder strips/hanging bits) are plausible for a Byzantine revival look, as are the gilded olive leaf headpiece.

The purple sash is a distinction reserved to the person of the Emperor/Empress?
That does work, and there are precedents in history for it.

The one thing I would mention is that late period Byzantine emperors apparently wore red boots as a distinction reserved solely for the person of the emperor.
Just a FYI I remember from somewhere...Probably Harry Turtledove, who is a professor of Byzantine studies as well as a science fiction author.
