You're going or a soft look, hence the predominance of greys rather than lots of contrast. Unfortunately it looks more like we're peering through a veil than it does a soft image. I would push the contrast up a little, and push the brightness down. Better to lose the whites than the blacks in this image, I think. I will accept that the flower is dimly lit, but not that the shadows are this super pale grey tone. Try for a more natural look overall, somehow? Leaving most of the action in the greys, and leaving things relatively low contrast is a good idea, I think it just needs a little refinement before it really sings here.
