This was your entry into the 'Delicate' challenge and appears to meet the brief for the challenge. As there is no information on settings and processing, I cannot comment accurately on how you got this photo to entry level without a certain amount of guesswork.
I am going to start with critical issues, there is a colour cast on the left cheek and jaw of your subject. I was going to say that the focus appears slightly soft, but judging by the eyebrows, there are signs of the image being sharpened. This suggests that the original was out of focus and sharpening rescued it but still left it soft. There is noticeable grain and I assume you used on camera flash which has lifted the exposure on the nose and round the mouth. Faces are really hard to light, and almost impossible using on camera flash.
Okay, now it's time to be kinder, the tight crop works very well as does the wispy hair. The subject looking down conveys innocence and as a childs skin is usually soft looking, it does give that delicate impression.
Overall it is a good portrait that captures what childhood is all about. The score is about where I would have placed the photo and I note that other commentors state a softness in focus. I hope this is helpful and constructive.
