I would appreciate some feedback on this as I do not know how to improve it.
Should I switch them up and have the cartoon duck point at the “realistic” one?
How can I make it look more realistic? Having a metal material and to color it white makes it look grey, almost black. So, any tips on white metallic?
It is the first time I’ve ever tried cartoon stuff. I used the freestyle render and I would love some tips on how to improve the black lines so they’re more connected and apply to more areas.
Your only issue as far as the metal is concerned is the fact that you’re treating it like a dielectric material. Most materials are dielectric. They have their fullest possible color saturation at their darkest areas, and run to the least saturated at the brightest lit areas. It’s the opposite for anything metallic. They go from the least colorful in their darkest areas to the most colorful. As this is difficult to depict with simply white or black, you should consider adding a slight tint to suggest a metallic material.
Onto freestyle! While I’m not an expert on this subject, it looks to me like you could solve your issue by either ticking the ‘smooth’ box in the freestyle settings (found in the scene layers tab) or possibly using the advanced setting and tweaking the sphere values. Alternately, you can get some fine lines by using the inverted difference between the softened and sharpened normals in the compositor, and tweaking the result with a color ramp (if your lines look too scratchy, proceeding it with a soften filter smooths it up nicely). Then you can simply multiply it onto your model.
