Not really. They lay flat and overlap each other slightly and the cord is woven through the holes. Unlike mail where the rings actually go through each other.
Lamellar plates are most common in the A or 'tombstone' shape, I but prefer the look of the D plates and because of their smaller width they tend to be a bit more flexible when going around curves. Plus, if I remember right, our evidence of early Nordic lamellar is almost exclusively the D plates coming from the Swedish trading post of Birka. Incidentally, Birka has become notorious is archaeology because if there is a random one-off object found in Scandinavia that doesn't fit established styles, 9 times out of 10 it comes from Birka.
Persona yes, heraldry no.
Persona is Anglo-Saxon by name of Aelfwine (Elf-Friend*) in south east England around 990. I chose that in part because the Battle of Maldon (of which the famous poem is about) is given the date of August 11, 991, which is two years off from being 100 years to the date I was born; so nice numerological alignment there. Plus later south east England opens up a lot of written sources not available in earlier periods, along with greater levels of contact and knowledge with the continent. While there had long been Frankish influence in south east England (there is some speculation that Kent was actually a subject kingdom of the Franks early on), we see greater evidence of non-luxury trade with the Franks. East Anglia had also been under Norse influence for a while so we get Norse visual influence without the stronger Norse influence following the overthrow of Athelraed Unraed and Cnut. Makes it easier to do research and opens up more opportunities to design and decorate the garb.
Heraldry isn't a big thing in my region, as most people just use the Barony/Kingdom heraldry when it is needed (such as hoods for court or war shields). Most people in my area have interests and personas from periods or cultures that weren't super big on heraldry; such as late Italian, late Polish, high Rus, or Viking Norse. The only people I know that make heavy use of personal heraldry are some of the old timers.
*I chose the name in part because so much of my interest in the middle ages came from Lord of the Rings, and a big inspiration for how Lord of the Rings / Silmarillion came about was Tolkien looking to reconcile and explain the differing ideas of elves in northern Europe society. On one hand we have the line in Beowulf referring to "giants and elves and demon-corpses [orcneas, which became orcs]", along with other stories about elves putting them in a firmly negative light, but we also have people being named "elf-friend", "elf-riches", "elf-counseled" (Aelf-raed, Alfred), etc. The name crops up all across germanic cultures in the early middle ages, but the aelf- root seems particularly common in England.
