Thanks Stwert,

I left the joints on the knees to be done in ZB, as with the bottom parts of the legs too, but glad you are liking it so far!

Have been messing around with a few ideas, and one I've decided to definitely do is his brain showing at the back of his head.
Here's a quick example of what I mean, not going to use this pass in the final model, will re-do it a bit better once I've tweaked my brain Alpha I've created.

More to come soon, just playing about with different ideas on various versions of him at the moment so may post some different ideas as they come up.
