the peony craze + the plea for help

we're back!wedding + honeymoon stories to follow. in the meantime, we've finally settled on a flower + theme for the wedding. it's amazing how everything else is falling in place. anyway, i would like to ask for your help finding a better image of the one below. or any ideas how to turn this into a vector image (that is the term tight?) so it won;t warp or screw up when we play around with it. really would appreciate any help. thanks. :)

can you imagine the endless possibilities for these beauties? here are some sneaks. hope you had a joyful christmas and wishing you a blessed year ahead.
