I'll say the grass was a cool idea, and critique it not being taken far enough. If you move leaves close enough to the lens they effectively work as a filter. Moving the camera should be the right idea, and the other option is to move grass or elements from the scene for an abstract or unpredictable result. As you may be aware, this could throw off the color balance although black and white is a click away. Don't worry about perfection while experimenting just push the envelope!
Thanks for the feedback. You made some good points.
