OK, you got a non-water liquid, oil of some kind, mixed in there, but the shot just doesn't work well. Lighting, focus, background - some or all of those, and maybe more, combine to just make this not work very well. 3
Shame this isn't very clear. Nice colour though. Even if everything looked to be in focus, I'd need more than this to keep my interest in the composition. 4
Shots of the refraction of oil on water... if so that's a little iffy on the challenge topic but I suppose something+water is not the same as just water.
I don't at all care for that bright green colour, something else would have been preferable. Too bad you couldn't get the iridiscent effect. The bright spots (light reflections, I assume) are a little distracting.
