I’m amazed on how important lighting is to a scene and to a character. I took thisblend file from this page created by Angela as a test character model and all I did was add a sun lamp that lights her straight from the top. I hit render and was surprised on how old the character looked just by adding simple lighting. So I took it and rotated the lamp 180 on the Y between frame 1 and 250 and came up with this
By the final frame the character looks 70 or 80, all done by rotating a light.
(If I shouldn’t be using this model just let me know and I’ll take down the link)
