Beautiful shot of colour on a dull and dreary winter day! Your lighting is perfect, like Phil says - but I think you could have used a smaller aperture to get a better focus. Either that or step away from the flowers for better DoF and then cropped the shot.
Hope you are not offended ...
This is a beautiful shot and actually I really like the focus i.e. the fact that the ones at the back are sharp and the ones in the front are fuzzy. I think it's very effective.
