I thought the thumbnail was a leaf until I looked a second time o_o It's so neat.. It's a nice change too, since most of the DD'd fractals are all curly and colorful, and this one is cracked and grayscale..
cool! if i had this flame i probably would have used green and named it "The Leaf" or made it red and called it "Veins" or something, and that would get lost in the depths of my gallery as a decent flame. your gradient and name choice though, makes it all more creative and interesting.. cool work!!
