I wouldn't make your border colours match the main photo's colouring though. Stick with either a simple white or a black. Especially with that first orange flower. It looses some of its colour and effect with the overpowering orange border. Looks sort of mushed together.
Actually, the person that bought it....wanted it that way LOL And then I forgot to save the original file, I accidentally used THIS as the original, so Im kida screwed!
