@paintguy: IMHO your image is not too difficult to trace (It’s like 40 points or so). Just make the outline of the flower, then add the image map as the texture for the outlined object.In the time it takes to looks for an alternate solution you could have the work done and be enjoying a working scene.
I just traced a sunflower, myself, not too long ago in After Effects. It was about the same quality as yours. There is actually satisfaction in doing the tracing. The sunflower is pretty simple. Just add a curve circle to the scene and sub divie it a few times. Then make the sunflower a background image. Then move the points in the circle to match the background image. After you are done. extrude the circle slightly to give it some depth. Convert the curve to a mesh so the array modifier can be used. Then assign the original image as the texture.
