This is deliciously wicked; I love it . The downside is that there seem to be "blue spots" on several leaves and along some stem parts (viewing on two different monitors.)
Sweet idea. Nice colour in the flowers, stems and leaves. The background seems very uneven - too bright in the centre, too dark and blue towards the edges.
Very creative! I like the way your border makes a striking contrast with the roses and the background. Normally dpc'ers give people a hard time about borders, but I really think it works here!
