In this case, there is no one main bottle as the subject. The idea is to capture the pretty coloured liquids of all the bottles but yet give a little depth to the picture.
If only 1 bottle is in focus.. it would means smaller DOF liao..but if you can focus just 1 bottle and pple will see it once they look..that'll be very cool...but anyway I like your pic..somehow the color is very like cosy and nice. Good work great idea
