The only real problem with the subject is those bottles really don't spill like this in my experience -- that's half the point of squeeze bottles. The basic idea is sound. I think I would have liked it better at a slightly top-down angle to emphasize the liquid.
Nice composition - and way to clean the glass you may have had dirty from other challenges! :) Good crop here, I like the way the cap is opened up - Why is there soap above the nozzle and would this have not looked better with a deeper DoF and fewer bubbles? Just a thought! I like this one.
Now this uses the same subject matter as another picture in this challenge. This image, however, makes use of the rigid red cap as a backdrop for the lively green liquid. Moving the red cap out of the center of the frame helps to draw the attention to the bubbles in the green liquid. The liquid has a soft, alive contour as opposed to the sharp, distinct outline of the bottle and cap. This composition seems much more alive and interesting to me than the previous post.
Good concept, but maybe having the background further from your subject might look even better. It would keep the "joint" where the background and bottom surface meet one another from showing.
Because the soap(?) in the lower half of the photo is a bit blurry, to me it takes the focus away from the liquid and more towards the bottle. Although to it's a pretty good photo otherwise.
nice composition. I'd rather the dof was set to accentuate the puddle of soap rather than the spout.. or mor of it at least. I tried liquid soap too. It was difficult, so bravo on getting it to look like soap :)
