It's the first time I see 3 sigs in 1 arranged this way. And most (if not all) of these sigs use the technique I call "stolting". To give a better idea what I'm talking about, here's my attempt to imitate the said technique on a portrait I found after being told about the technique by Stolt himself.
The second sig is probably the best, from the production standpoint at least (it seems to be way more complex in its use of decorative elements), but it's hard to pick which looks the best. All in all, nice sigs.
P.S. I just came here to say "stolting" and to give the person who'd be replying below a harder time doing so.
