soap is liquid, that's fine. top-down shot, more interesting than some. I still am hung up on the "squeeze bottles really don't spill that easily" thing. Refraction is cool.
I like your shadow and backlighting - I don't lik ethe bubbles still in the bottle or the dots that mark your detergent spot - and the red nozzle is in the way of the more important subject.
This image doesn't have any good focal point in my opinion. The red cap draws the eye but it doesn't seem to have any action. The action seems to exist in the liquid spilled (because of the bubbles) or in the brilliant green refraction just under the bottle.
A shame the pool of liquid couldn't be as intensely coloured as that in the bottle - lets the shot down a bit. Good clean well lit stuff though - but a little lacking in more elements than design
