I've also written the blazons for the shields and crests. I have some doubts about a couple of them so I'd love some help if there's something wrong with them. I have no idea how to blazon the first crest, and I don't know whether the blazon for the enflamed(?) towers or the chains are correct, plus I'm not too sure about the blazon for the man's clothes in the fourth crest.
