After long work I present my first ... well, sort of good CoA made in Inkscape. Again it is based on a Code Geass timeline of mine, actually the shield is a repost of my earlier "Arms of Southern Britannia". Quoting from the description of that file:
"In this timeline, the South American continent under Duke-of-Lancaster-and-Wellington-turned-General-turned-Emperor Charles IV Beaufort-Wellesley (therefore the CoAs of the duchies Lancaster and Wellington) broke away from the realm under Empress Nunnally vi Britannia."
This is still the premise. However now I offer to you three slightly changed, VECTORISED versions of the same Coat of Arms:
The field party per pale, dexter Gules three lions passant Or langued and armed Azure, Chief a three-pointed label Azure with three crosses Or on each point; sinistre quarterly, I and IV Gules a cross Argent surrounded by five bezants Argent (2-1-2) in each of it's corners, II and III Or a lion rampant Gules langued and armed Azure a collar Or. The whole surrounded by the Garter; for a Crest, upon the Royal helm the imperial crown Proper, thereon a lion statant gardant Or imperially crowned Proper; Mantling Or and ermine; for Supporters, dexter a lion rampant gardant Or crowned as the Crest, sinister a lion Gules armed and langued and collared Or, both supporters holding a banner of three fesses Azure, Gules and Vert, parted by two bars Argent; Motto 'Dieu et mon Droit' for a compartment below the shield, with the Union rose (England), shamrock (Ireland), orchid (America) and thistle (Scotland) engrafted on the same stem.
