Big, fat, sad, POUT

I am so disappointed in my photo shoot from Saturday.  My friend asked me to take pics of her girls in an orchard..matching dresses, very girly.. They were one of my very first families to shoot and the previous pics so horrible.  I was determined to do a better job.  I knew on location I was struggling- but thought I got some that I liked.  But, on my computer there isn't the clarity that I was hoping for.  I am so sad about it. I posted an image on my fb group to get feedback about the clarity issue and got a little slammed :) Grrrrr.....  just so bummed.  I thought for sure I would have sharp focus with a smaller aperture.  I don't know if it's me or my lens.  But, I do know-  I'm super bummed.  It wasn't easy anyway, with shifting light, mosquitos, sibling squabbles, and a 3 year old who was DONE :) Here's one-- it's ok.. but just not as good as I thought it was in-camera. Not sure if I like better with vignette or not.
