Definately not a traditional spiral. I like that you were gutsy enough to shoot a sharp angled and non-traditional spiral. A kind suggestion if I may... I think this image needs a little more contrast so that you have part of the image that is pure white and part that is pure black. When I started in photography it a point was made to me that a B&W image should have a pure white and a pure balck even if they are small. I hope this is helpful. Peace. --Will
