Thanks guys, I really appreciate it!
It really varies a lot from character to character. For example for the Dragon I was given a nice piece of concept art to reference as I went.
Usually a 3 Quarter view or Front, never both though. When I have a concept to work from I'm usually let off the leash a bit and it's my job to interpret how to best incorporate the concept design on top of an existing actors face. The concepts are rarely using the actor's proportions to build from.
Sometimes requiring the human proportions to shine through, and sometimes completely changing them into monster features.
I have to bounce between workflows a lot because I might be going off a concept for one character, and another character in the same episode might have full on Prosthetic makeup applied that I have to match digitally.
I like working from a concept a lot, it's awesome to see something come to life in 3D.
But working from a prosthetic reference can be pretty cool too.
I always try and find areas to improve upon since the Digital version will be used for all the close-ups and any Lip-syncing shots.
The last example would be like Captain Renard's hand renders at the bottom. That was just a go for it kind of scenario where I was briefed on what they were after but wasn't provided any specific reference.
Hope that's clear enough..
