Myer, This is a very nice first try at Fractalius. I see the Butterfly but would like for it to stand out a bit more from the BG. Are you working w/ photoshop cs3 or 4? If so you could add a layer mask and try to mask back in the mushroom? or whatever it is in the center, I think that it will help the BF stand out. Nice colors.:)
First open your image in cs4 then make a copy >ctrl J (for windows)
then go to your layer palette and add a mask. (this will be the rectangle w/ the circle in the middle)
that will add a white box next to the image on your duplicate layer.
then you can select the brush tool (set to soft or zero hardness)and using black.
then start to brush over the image - you will be revealing some of the original image.
Hope this helps.:)
