Manjunath - am a big fan of negative spaces in images or any form of art and this will add to the list. I have to say i have been too influenced by this concept of negative space (or what Ganesh calls it as Positive space) from the master himself
Liked the approach here but my suggestion (if i were you in this situation) would be either a high key image rendering bg as close to white and also a probable portrait orientation to get the contours of the birds (size) and the plant/twig in consideration.
