If you want to make some artsy image out of these two flowers ( I am not that romantic and do not think plants ever fall in love, even if they touch each other, so to me personally it is a boring image, sorry), but if you want to add some color and interest to it, take some colorful fabric or a bright contrasting hat, anything bright you have that contrasts and complements the color of your subjects (or shall I say lovers?) and put it behind the flowers, open up the lense to blur your new background and you will have a much more appealing image. Probably. Or probably not - but it is worth experimenting.
