First impression: Do you have an underwater (...undermilk) camera? Great angle on this shot.
Composition: I get the feeling that this was taken looking directly up at the bubbles. The only distraction is the small bit of white in the bottom left. If you crop that out on the vertical then the effect is multiplied.
Exposure: The image seems just slightly dark though I think this was probably on purpose so the milk was not so obvious.
Impact: This image has a lot of impact giving the impression of being underwater. More impact I think would be achieve if the small portion of visible milk on the left were cropped out.
Well done. Keep experimenting, no matter how messy things get.
Now that's an interesting idea. Unfortunately, it didn't work very well as an image. The focus is pretty soft (maybe some more DOF?), and the bubbles are just messy looking. 4
I like the effect you've gotten here with the white milk on bottom and the blue bubbles on top. Also like the blue cast you've achieved but am not crazy about the way the milk is lit with it being bright on the left side and in dark shadow on the right. Maybe more diffuse lighting would have been better.
