Ah, got it now, thanks! Yeah, the basic shape is utter fantasy, I'm afraid! The emblem seems to be just a "melt-down" from a generic Trajan's Column style.
The spiral features we generally call "spines". They seem to date back to the wooden spines that were part of the boss way back into the late Bronze Age. Such features survived to the end of the Republic, at least, and after that became part of the painted motif (or applied thin metal, etc.). These are roughly 2nd to 1st century BC:

The rectangular features on that one
shield are tabulae or tablets, shaped like a writing tablet. You can see them in artwork and carvings of various sorts. But there should be lettering or text of some sort in them, presumably the unit number and/or name, etc.
One subtlety that I see going wrong quite often is that the Romans never seem to have any horizontal feature projecting from the boss without a vertical feature. You *do* see vertical spines with nothing projecting horizontally, but not the other way around. I suspect folks are still copying the Ermine Street Guard, who got it wrong 30 years ago and haven't changed.
Also, people tend to over-size the wings, but they generally have to fit next to diagonal lightning bolts, which limits their size.
Vale!
