I like what Gary did with the textual part of the logo.... it is a natural for the serif and lower case/uppercase mix...
My visual theory is somewhat different.... I feel that people are the focus of SmoothStone Consulting, and most observers will not derive any substantial meaning from the current graphic. They may discern that there are stones and water included.. but it still does not provide them a visual clue as to what you do.... potential clients literally require to be spoon-fed your core business process message... or, they will not "get it", as their hectic lives leave no time for graphic puzzles... unless they are literally intending to waste time...
Although it looks cool, it doesn't convey purpose, intention, possibilities, opportunity, conviction and a host of other subtleties that are essential to getting your core message accross at a hurried glance....
This is a very rough idea but it serves the purpose of demonstrating the addition of the human element into your branding....
Cheers,
Chris
