I'm all for the noise - that includes the textured noise - it's sort of enhancing the blur dynamic which is the essence of the shot. Strictly (or pedantically) speaking, I think noise is extraneous and irrelevant to context by definition. As these 'fuzzy bits' are neither extraneous nor irrelevant, then they're not really noise either. I think you're off to a flying start anyway, just about everything about this picture (use of b&w, composition, focus/not focus, blur/not blur and the models who won't do stuff like this when they're all grown up) is pretty damned impressive. So there.
Oh, Charlene, I love this photo. I am a big fan of the artistic blur, and I think the motion adds even more delight and playfulness to the scene. I'm happy we'll be doing a side challenge together again! I love your work, and I love hanging out with you :)
This is a really nice shot, I love the feeling of motion and energy. Not too sure about the paper texture you've added though, I think the shot is good enough to stand up on it's own without it.
