Here's my new tidy Kryten.
Based on how he looked around series V of the show, this is a remake of a model I made when I first downloaded Blender - it was a very bad model really but the likeness wasn't bad, think I've improved the likeness though, and the topology is good now, I didn't know what topology was when I made it the first time round. All polymodelled except for a bit of sculpting around the eyes, but I need to improve my sculpting - the eyes are the bit that needs the most work really.
Mask material is just a procedural sort of silicone look with a bit of subsurf.
I was aiming to get something that had as good a likeness as the Sevans Kryten model from the 90's and I think I've done it so I'm happy.
