Thanks for your comments eyeryone. Mary Sue this is the colour of the card, but its a purple shade not blue. You can get almost any colour you can think of, they are quite handy for something a little different from the straight black background.
Lovely flower but the background distracts the eye. For my eye, it is too strong a color, too close to the subject in hue, and too bright. A darker background, even in the same hue, will work far better for me. This image will also make a stunning B&W conversion I think.
Lovely, the off center framing is nice. Ditto on Harvey's comments about the color. You described the background as light card...was it that blue color, or did you change a white card background into blue with PS?
