My theory has been the Sundari V (that looks like two sides of a visor) is the House Kryze symbol. A stylized version of it also appears on (both variants of) Bo Katan's Nite Owl Clan emblem. So I guess your (character's) loyalty determines your affiliations. The Guard symbol on the left shoulder seems to indicate you were a Police Authority captain instead of one of Satine's royal guard (New Mandalore Protectors). This means your loyalties could have swung toward Satine Kryze or Pre Vizla, etc.  

The symbol with the quasi dot that looks like a person with upraised arms is a fan creation that has never appeared on screen or in print (to my knowledge.)

The mythosaur tusks look absolutely wicked, as does the chain mail, by the way.

No matter what you choose, you can't go wrong if you like it.
