looks like ya got some clipping mask behind that smudge clipping mask is a good effect dont hide it
you could use it to blend the render as well as create flow i love clipping masks
putting your smudge behind the mask would look better imo
not much flow try to stay away from using the whole effect fractal i think too many lines everywhere instead use pieces where it creates flow rotate and flip re size the effect to place it where it looks good and erase the rest
