Great art is all about moving the observer in some way, touching their hearts, conveying and inspiring any combination of mood, emotion, story, wonder, beauty/ugliness, message, idea, and thought.
Sculpture is a really good media to do this in, and this is certainly a form a sculpture. These pieces tell stories. there is so much detail in the faces that you can easily read the mood and attitude.
Some of your work really does move me, like when you sit back as "Oh my God, look at that".
In this piece you can see his motion and movement, his towel is swinging, his penis is swinging, his head is in movement, his calf is in tension, there is attitude and energy.
