Bursted bubble like details on material I'm trying to generate a material somewhat similar to what I got on a picture I took, just to develop material/texture creation skills, but I cannot get the details that appear to be tiny busted bubbles on the real photo.

I'm guessing this should be achievable using voronoi textures, but I cannot get even close to it. Can I get some tips to help me acheive that look here?
You were pretty close. 

I've used Voronoi for the bubbles and mixed it with some Noise.
First Color Ramps are for tweaking "contrast" of the textures and the last one is to give proper colours to the bubbles.
