As I'm not a fractal artist, I can't accurately give a good critique on this, so I'm simply going by my own interpretations. First of all, I love the style of this. The bare flashes of light here and there really accents each feather nicely, if that's what they're meant to be. In the center, they almost seem to band together to form a flower with a beautiful contrast of colors. This almost seems like a field of black roses, hence your fitting title. Honestly, one of the best fractals I've seen as of yet on this site. Well done!
