Vestmann, may I ask you a question?

What do you prefer,  your own link the painting that took 70 hours to complete or any of the spotless Maya/3ds max renders above? (I hope I don't need to tell my own opinion.. )

It is nothing wrong to "reduce fakeness" as much as possible. But when your render is finished, do your postwork. That is the art bit. The proud statement "no postwork" is that of the hobbyist playing.
