ah forgot about the jagged crown...so i guess that'll be the player's "crown" then?
Though the flag/banner still seems....idk, bland? Maybe try spicing it up, try throwing some dragon runes on there or something, idk xD
I have to agree that looks much better than the iron helmet (seriously, it's only iconic from the audience's perspective, which really makes the banner more of a 4th wall breaker than anything. It'd be like having a symbol of a guard getting shot in the knee. From an in-universe perspective its not very iconic and just looks rather silly. And personally I've
never liked the idea that the
crappiest heavy armor in the game is somehow the iconic armor for the
most powerful [wo]man in skyrim. I mean... really?!) whereas the Jagged Crown does have a lot more in-universe significance. but I also have to agree with Drewan that by itself the banner is still very much bland. But you're on the right track now, at least.
One thing I might suggest however is that you include an unused "blank template" with the texture files (and make these loose by the way, even if you put everything else into a BSA) so that players can create their OWN symbols for banner/shield coats of arms if they want. (Sort of like what TalkieToaster did with his Robco Certified mod)
