Beautiful. I personally would have move the rose in the upper right corner but still a very dramatic, powerful, gorgeous picture. I would have also tried to avoid the shadow in the bottom right corner. Still, great job.
Well, I just discovered you, so I'm going to say Welcome to Caedes, even though I see you've been here for a year or so. I love this take. It's the kind of arrangement I like to see with the delicate beauty of the flower against the roughness of the concrete plus the shadows make this a wonderful upload. It's in my faves, and thanks :)PJ
