Shiv, the ladder like branch and posture of the bird gives this image a graphic feel. I like the high key background too. I tend to think brightness is a bit more and contours of the bird seem to merge with the background. I would experiment with slightly cutting the mid tones a bit which in turn may affect the abstractness however. You may need to experiment a bit with that. I love this one a **lot more ** than a nice portrait of the same bird in good light in a nice green background
Thanks for sharing..
