My concept: A path to a new horizon. The scene is actually an abstract human figure in a joyful pose.
The idea is that your practice is the PATH to the bright horizon which will end in a successful result. This little icon tells your whole story and brings a feeling of joy to those who see it and may be considering your services.
Its simplicity makes it work well in 3D web applications but it can be scaled down to a simple print form without losing beauty or meaning.
