Lookin' smooth. I know what a complete bastard some of those organic shapes can be.
Never was a fan of those blocky protrusions behind the head though. Like some Romulan shipyard worker found out he forgot to put in 20% of the rooms after the ship was built
Have you tried the Chamfer modifier?
It has a few more options than the tool has.
I find it quite useful since you can make a preset if you get a chamfer that works for a certain situation.
(oh, and don't get your hopes up on bugs getting fixed in Max2020 or 2021 )
