I'm sorry you're disappointed by the first round on a sculpt. That's why I ask for input. Many eyes see things from many angles.
Rather than be negative, why not be constructive and help make it a better sculpt? I don't know if you are familiar with my process, but what I do is post photos of a piece while it can still be worked on and made better, then I ask for constructive comments. Through this critique I aim to make the best heads available. Perhaps, being but a mere human, I cannot always live up to that lofty goal, but if you look at the evolution of most of my work I think you may agree that with the help of folks here who serve as my extra eyes I've been able to make a few passable likenesses.
Again, I'm sorry that a first draft didn't "rock" you, and I'm sorry you're of the opinion that somehow if only it had been quicker it would have been better, but I refuse to crank anything out just for the sake of having something done. I don't do that. I will not undermine my integrity that way. If something is worth doing, then it's worth taking the time to do it right.
This is not an easy nor simple pursuit. It is an art, if I may risk sounding a bit pompous, that takes a lifetime to master. And no, I have not yet mastered it, even after having spent half my life and my entire professional career pursuing it. I'm not so arrogant as to deceive myself in that fashion. That's why I ask for input! And I treat EVERY job as if it was the most important job I have ever had. I like to think that my friends and customers come to me for these heads because they see that something extra in my work, that passion, that concern, that dedication.
So, if you have specific points that would help to make it a better sculpt, to make it, in fact, as samueljd so generously says, "the best Kirk sculpt out there", then please do participate. Together, we can make these sculpts "rock".
