Just as the arrangement and proportion of form changes as life-forms increase in size, so too must sculpture undergo changes with larger scale. Ideas and concepts also have their unique scale - from the "passing fancy" to the "million dollar" idea.
It is not enough for the sculptur to simply enlarge a smaller work. He must first make sure that his concept has the power and presence to aesthetically function in a larger size. A Chihuahua created the size of an elephant would remain simply a large Chihuahua.
When an idea is created in the perfect scale to match its presence - great art is born.
Fine monumental sculpture should feel as if it grew on site, that it has always been there, and always will be. Its size and presence stimulates a response from the viewer that is akin to that experienced when seeing a beautiful mountain or a magnificent landscape.
Just as a mountain seems to change with every season, monumental art constantly presents a different light and shadow pattern.
