This is addictive isn't it ;) Am guessing milk with coloured gels on your speedlights? I'd have given you another point if you'd tidied up the stray drops.
I don't add on or knock off points for manual shots or kits - both are really difficult to master and shall check back to see how you shot it (bump of 1 point).
What can I say, This is a great portrayal of what can be achieved with such a shot! The clarity and sharpness is out of this world! I love all the milky colours and the fact that the splash is actually facing the viewer.
