YOu have done very well and seen teh feedback I have given others - I prefer teh curves of 128 and 132, but they need to look more liek an S. I know difficult. Maybe make the head a small insignificance and curve the top round more. Then the S we could use as a symbol on its own as well. May be more abstract.
The text font I think matches the more right angled shape of 135 and 134 and doesnt suit teh curves of 128 or 135
