Eyes: Well, they were the last thing I did. I simply went to the internet and found a nice picture of a real cat eye. I then used the roller brush and the rectangal stroke to place it, and scaled and until it fit. I did not mess with that part much.
But I did mess with the shader quite a bit. It is based on the Toy plastic shader, with some ambient to make the glow a little.
The eyses are a little different in size, not that you mention it- I need to fix that.
What do you mean by flow, and which bumps are you taking about?
Thanks for the comments!
