I know it's a matter of taste, but I find the colours a bit muted in this shot. Especially with the green theme, I wish the leaves had some more punch in their greenness, and a bold red rose to contrast that.
Not green enough, and it feels like too much is going on. I am a rose freak, I love them completely, and can never see enough of them. Here though the color that I love so much is faint, and it feels flat. The other thing that I love about roses, is the smell, and when I scratch the screen it doesn't smell. :)lol.
