Nice shot, great lighting, decent on the textures, could be a bit sharper perhaps, but good enough, I just don't agree with the line above the flower, I have no idea what it is, sorry to say it does distract enough to hurt the score. Id do some spot editing and remove it. 5
I hardly ever like photographs of flowers, but this is a 'hardly ever' moment. It's no coincidence of course, that you chose the title you did.

And what if excess of love
bewildered them till they died?..."
