Lovely photo. On the manipulation deal, if you're going for documentary/storytelling/journalism, then certainly no. If you're just making pretty pictures (and there's nothing wrong with that), then I think it can work sometimes, although, if there's something in the frame that's messing with your composition, it may be better to move your camera, but there we are... :) Rock and roll!
Thanks! Absolutely agree with you about moving the camera to get the best possible composition!
