Sandya.. I never really got the why of water marks... but then...I think of art as a recipe....just because every one has the same ingredients....doesn't mean that..they will produce the same cake...but then again...I can't imagine any one wanting to steal my art...and if some one chose to copy it ..Not only would I be flattered...I know they would never do it exactly like me...I find your work highly recognizable as yours....and that's a good thing...sue
