@Ashish and Sravan - Thanks a lot for your comments.
@Erin - Thanks a lot for your views. I have a color image of this which I equally liked with high end greens and still the shades were visible. Will post the color image in the illustration forum.
@ Ashwini.. good to hear your comment after a very long time
thanks a lot for your comments. I have a higher resolution image which I can post in the IF.
