This is an interesting piece due to the technique used to color it. I used a method called iteration coloring, which means that I used multiple layers of the same fractal for coloring, but rather I changed one setting that sort of makes makes the fractal look like chunks in the shape of the original layer. The key is to set your layer blending to Color and adjusting your opacity.
Keep in mind this will only work with Ultra Fractal coloring algorithms that have the Iteration setting. Otherwise, give it a try!
