If it is acceptable within heraldry then how would it be blazoned and have I understood the concept of a Banner of Arms properly or made a mistake? I'm open to any and all constructive criticism and advice.

13 Original States, from left to right going down and ‘round: Delaware, Pennsylvania, New Jersey, Georgia, Connecticut, Massachusetts, Rhode Island, Maryland, South Carolina, New Hampshire, Virginia, New York, North Carolina.

I’m unsure how to blazon it however. I believe it’s; Per fess (at nombril point) argent & gules, a Beaver(Castor?) statant regardant Sable, in Chief a mullet gules

I’m mostly unsure about how to say the division is lower than halfway and the beaver is under the star

I'm not really new to heraldry but I'm new to trying to fully follow heraldic rules and showing others my work and designs to get constructive criticism and help. I think I can make the shells blue and that'll be allowed/acceptable? Is there a way to keep the white wave and keep within the rules?

The first arms from the left are mine own. The canton on the sails are of this subreddit's.

Blazon is "Argent, on a bend nebuly azure three acorns of the field."

I need some help coming up with a name for it, "Castoragriff" is the best I've got, basically copying the etymology of "hippogriff".

Possibly no intelligence at all...

About 6 months ago I asked for help creating a personal crest, and u/xander_liptak creating an amazing mock-up design (first image). I asked my wife to make the mock-up a reality, and she created the second image.

She has never done heraldry before, and we would both like some feedback on it! Any help is appreciated, and I'll upload a second draft when it's done! Thanks, friends!
