Exposures all over the place and same goes for the white balance. Some general post processing would really help these out technically. Focus also seems a bit soft and not loving the backdrop. I took a look at your EXIF data and things look reasonable so maybe take a bit more time to nail your focus and meter correctly on the kid rather than the backdrop or the nose of the stuffed animal. Keep shooting!
Take the feedback in a positive manner. Learn composition first. A great focus and exposure means nothing unless the composition is good, that includes but is not limited to lighting, subject position in the frame and background.
