Why would you add anti alisaing on the outer side of outlines? Sort of defeats the point of them, imo.

Thank you!
I'll try it out!
 

Hello :)

The animation look's good but you may wan't to increase contrast so the shading will look like more like metal instead of plastic.

Because you set a background and don't specify any colors number, you may also wan't to add a little bit of anti aliasing on outlines :)
