Either the poster is saying, "in capable hands you get a picture like someone using a fine musical instrument" or "in capable hands you get good pictures, when you give it to a hamfisted monkey who shouldn't be trusted with a guitar, you get this..." Not sure which, but judging from the response to this, I think it's the first.
or from bad Google Translation, I think the poster does not like the pose and composition:
"I would, incidentally, did not use the photograph as advertising reaching a "balalaika from the camera". IMHO, the space is too zazhato, posture model creates the impression of instability, "hind leg, knee, looks inharmonious. Front of this model should not be so removed, imho, they look any soschurennymi. Of course, this subjects." (is subjective?)
