Ribbons

The jaggies are from the fact that the app you're using doesn't have anti alias capacity OR if it does you haven't used it... if there isn't an antialias option the simple solution is to render large file sizes and then downcovert the image in Photoshop using "Image size..." to your intended resolution making sure that "keep proportions" is checked. Photoshop will interpolate the image and the result will be a *smoother* contour. Still, this image is gorgeous and reminds me of the American Art Deco movement... very lovely. Well done!!
