As for Septimius design to me, it felt simpler. Our view on Septimius was always clean and straight he is the bad guy you hurt and terrorize people for fun while making sure he is well taken care of himself. So just use triangles.
So I just when thought version after version till I reach something came to like and keep working from there.
Septimius O'Hare is very scary who has terrorized the local families in a bid to take over the harbor.
