Photo editing and Retouching

Photo Edit No.1 (Picnic Photo): a) My Nephew feels the photo make her look heavy especially around the middle to upper sections of her body e.g. mid section where dress appears to flair making on up. Whatever you can do to skinny her up would be great. b) A very minor slimming of me in the mid section (far right person) c) Adjust photo colors as needed. Note, this photo will be place din a Holiday card no larger than a 5 x7... However, I still want to keep high quality resolution of updated photo. Your photo shop color enhancements are a plus! Photo Edit 2: Cat and Dog picture attached. I want to combine the two pics (animals in same photo) into one picture so it can be placed on back side of holiday photo card. I would cut out each animal and place into one photo with plane white backdrop or whatever looks best.
