I agree, a great pic.

I also agree on the intersection problem -- maybe a csg?

And any contact will be a plane - not just with other bubbles. So the
bubble on the ground would also be a hemisphere-ish thing.

Also, the bubbles look sorta solid - like glass spheres.  I can't
exactly say why.  Maybe the surface is too clear?  Bubbles often seem
just slightly swirly.  Or maybe it's an IOR thing -- there's some sort
of 
refraction going on that just doesn't feel right.

I'm not trying to be super-critical -- it's a neat pic with nice
composition!  It could easily be Stunning with just a few tweaks.
