This was more of an exercise rather than a new version because I still prefer the old one. It's not obvious, but there are some significant changes for this version, among them:
-larger head (perhaps too large?)
-obviously a spiky sail achieved by adding two more pleats
-and the biggest difference is this one uses a 10 x 10 grid rather than a 9 x 9 one!
