Let's get one thing clear, the pics posted here are supposed to be "ART"...Art is subjective, meaning what one person thinks needs improvement, another may feel is brilliant. Therefore what makes one an expert, so they have the right or expertise to tell another person how to improve their pic. so basically it boils down to if you like the pic say so, if you don't move on and say nothing.
being around here a while I noticed, most of the know it alls, that said this or that needs improvement, were the ones that weren't very good at this themselves. So to finish this story, if you want hits and comments post flowing hair and boobs, if you want to actually learn something try doing something different, probably won't be a popular pic (unless you are on the popular list here), but it will make you grow in your ability.
