Dramatic in a subtle way, & while I'm not exactly sure how much I like the black, I gotta admit it makes your center spirals kind of sit up & say ""boo !". One thing I DO say is it's the kind of fractal you just kind of have to study...because you just can't glance at it & say awesomeness & trot off to FB.
I'm glad you voiced some constructive criticism. The black borderish effect was sort of an accident, but I kept it because it was at least different for me.
This is not a work that I'm emotionally attached to. I learned some things in making it, and I'm proud of the craftsmanship I put into it, but I don't consider it one of my best. But it's still nice to hear that it's a work that invites study.
Your FB comment is priceless. Thanks for making my day!
