"I don't know why the links provided to the ZBrush
beta 4R8 gallery link could not convince you?!"

OK, now I understand. This is a religious discussion for you.

Obviously from your gallery, you are not a master of Zbrush, yet you want everyone to believe it can replace all other modelers. Good for you.

I suspect if I were only to use programs where there were 'best-in-class' designs created, I could start with just about any 3D product; SketchUp, MoI3D, Rhino, Maya, 3DMax, 3D Coat, Blender, Modo and others all have examples with similar or better outcomes.

As one who works as a professional in the industry, I choose to not proselytize how everyone should work. I offer suggestions and my work experience. That's it.
