Hey Russ,
Question:
Once you finish a sculpt, I don't expect you to look back since you have so many other sculpts you are trying to finish, and trust me, I'm happy to get whatever version of a character you make because it's like gold.
However, in older conversations, Chris Howes would often say once he had a likeness down, making a variant by changing the expression wasn't that big of a hassel to do. I don't know if this is actually true or not, but if it is, would you ever consider making a grimmer or frowning Pertwee at some point by modifying his expression? I ask only because of this sad, sad example:
As you can see here, Martha should be threatened but is completely ruining her scenes (laugh).
I'm good with a smiling Jon, but of all the Docs, he can actually kick-butt in the Venusian arts, and it would be nice to perhaps have a Jon with a look of self-rightious indignation as he clobbers some Ogron hienie, looking serious. Just a thought/hope?
