1. your subject is orange, you have cut her fingers off. your editing is very evident where you have cut her out and blew out the background to white in post. The eyes are very over sharp and the rest of the image feels like it's soft and almost out of focus because of the eyes. Sharpening the eyes is common practice, but it has to match the rest of the image.
2. The series is out of focus. Especially the second and third ones. It's adorable! the contrast is losing you a lot of details. the face is a bit DARK compared to the dress. Converting to black and white should actually be done with color filters to allow you to decide what tones are darker and lighter-it's a little complicated and takes some real work to learn to create a good black and white.
3.I am sorry, that is creepy. There is a ghost of a face and BAM! The eyes.
4. YOur editing the background is EXTREMELY evident in this one. If you don't have the light power to blow white out to bright white don't shoot white. It will cause this problem every time. Your subject's face is MAGENTA/hot pink. The focus and everything look great. The cut of the dress does effect this image. If you had wanted to print thisas well as the others to any standard size but a 4x6 you would have MAJOR problems with the crop. Back up and leave yourself some room for crop in post processing. In doing so you won't crop important parts of the image either.
5.Your editing is very evident on this one too. The lens distortion makes this poor little one all forehead and ears.
The eyes are a LITTLE sharp, but it's pretty decent on the face. This is the best one of the lot.
