I tried to find the macro image, to see if this was dark or if it is an effect of the Fract application, which can happen. I might have lightened the BG area of the butterfly a little if it were mine. But ...
Ken, The fract. work looks cool and the dark BG is nice, I might like it rotated so that the wing on the right was coming out of the corner a bit. It may not look great but I would like to see it before I made up my mind. Very nice work.:)
