I like the way you used the curve to make the bone. I think you did a great job. I guess I don't really like the design of the bone as a "dog bone" or a leg bone because it looks too much like a dog food logo.
I think you have good ideas and are on the right track though...
sorry for not seeing the vital part that you want...my bad. hope you like this..its more like an abstract. its in vector format.thanks for the feedback by the way.
