Cel-shading

Post a little more code if you can, but a few questions.

First, what is the effect you're going for? The picture you provided looks decently cel-shaded, with a few anomalies in its head and right arm. Is that what you're looking to correct?

Second, are you normalizing the vertex normal before dotting it with the light direction?

Third, how are you using coord?

This is the effect that i would like to get

I Get this effect using this set of normals

But if try to recalculate normals of the mesh using this algorithm

core::vector3df a, b;
a = vtx[idx[i+0]].Pos - vtx[idx[i+1]].Pos;
b = vtx[idx[i+0]].Pos - vtx[idx[i+2]].Pos;

core::vector3df c;
c.X = a.Y * b.Z - b.Y * a.Z;
c.Y = b.X * a.Z - a.X * b.Z;
c.Z = a.X * b.Y - b.X * a.Y;
c.normalize();

i get that effect i shown you before (http://85.25.18.122/snap0058.bmp)

So i suppose the problem is on calculating normals.

post jpg's not bmp images, i for one dont view bmp's on the web
