thinking out loud here:
5 is a nono for me cloakwise
2, 6, 7, 8 too plain for my taste
pattern of 9, although its bit dwarven-ish, which i like... but still... nah...
this leaves 1, 3, 4 & 10
I think 10 can be very interesting. In this setting it seems a bit simple, but if you set a dark background with a light foreground (e.g. 'gold' on dark red) ánd if the emblem fits right into the shield, this could be cool. Could be a ++ for me.
1 gets a +/-, 3 and 4 get a +
So voted 3, 4, 10
[edit]could only vote for 2 patterns, so ditched 3, cause it wont look as cool on a cloak IMHO[/edit]
