Thanks all.
Dave, I will be texturing... probably procedurally for a lot of stuff, since I don't know anything about C4D's uv mapping yet, but I will have to unwrap the hamster at least (not started yet).
Nilla, no worries, the surgical instruments and the hamster are for different projects
Ben, yes, I'm a big fan of Eric Keller, I've got a couple of his books, haven't worked all the way through them yet.
And I'll be changing the lighting, the test renders at top came out creepier than I intended. It was meant to be just a simple three-point setup to show the models, haha.
