Unity Pro Toon Shader Question

Hello everybody. I have a very quick question for you. I use Toon Shader that has come with Unity pro to make my game toon shaded. I use Unity's default bootcamp soldier as enemy, and I used toon shader for it. It looks just like I wanted when I'm close to it. Like this:

But when I'm away from the enemy, it looks really bad. I think the outlines gets together and this happens :

Is there anyone know what can be done ? There is no settings in shader too, only I can adjust outline width.

I also thought of using crease image effect but it is not so effective agains the objects in the action you know, it justs outlines the edges like terrain's edge.
