It's an interesting idea but it doesn't quite work for me, there's a conflict of interest. Is the subject the motion of the bubbles or the refracted colours in them? Given the pattern of coloured paper I think it should be the latter - for which purpose the bubbles need to be sharp. Look at the lovely effects that you are getting - particularly the red and blue showing through the bubbles seen over green card. I'd love to see that hard, sharp, sparkling, like glass marbles.

I am left wondering what it was that you originally set out to do.
I like the pattern of the coloured paper very much, radiating from a central point. What I also like is the interesting patterns that paper is making on the most prominent bubbles, those near the centre, on the yellow and green. I agree with Moira, and if these were sharp, they would provide you with a focal point, an area of immediate interest.
I would suggest that you don't stir the water, but if you still want the circular motion of the bubbles, then you are going to need a much faster shutter speed. I have to admit to liking the circular motion and contrast of the circular pattern against the triangular patterns of the coloured paper.
I would take this further and try different settings. For instance, a larger aperture would give you one small group of bubbles in focus, allowing the rest to be blurred, which is quite a nice effect.
I have done a modification where I cropped in order to make the composition a bit more interesting, having the centre to the left, ending up with a square format. My intention was also to emphasize the most attractive bubbles, which I selectively sharpened, in an effort to demonstrate my suggestion in the last paragraph.
