Being an ex-photo lab employee, my biggest pet peeve is in color ballance. #1 is too red, #2 is slightly red, #3 is just a bit too cyan but real close, and #3 is a bit too red. #3 would be the best shot if you got closer to her face. The trees overpower the shot but make a good framing choice, just get closer. "axy" is right...get down on their level for proper perspective and bring stuff for the kid to play with. Ask the child to bring their favorite toy. Pets are a good idea, just be careful with the wardrobe...wouldn't want to try and pry a cat away from chiffon/lace. After saying all that...just relax and have fun!!
