Yes they are, but they're not looking too delicate here - especially with the facial expression on the girl in green. Nice sport action capture, but I'm not getting the "delicate" feeling from this picture. <5>
This just doesn't say delicate to me at all... in fact... it says the total opposite of "girls are delicate" here they are getting dirty and competitive. As a sports photo, I would suggest a higher shutter speed if possible... also make sure that you check for your horizon line to be straight... they would most likely not be playing soccer on a tilted field, so I hope that the fence would not be tilted... Fairly good emotion on their faces, especially number 13's I'm not sure that this is quite clear either, but that may be because of lower shutter speed, or the focus may be in the wrong spot which happens easily when you are shooting at lower fstops to blur out the background... also check your exposures, the ball and the girl's white shirt seem to be a bit blown out.
