The clarity of this photo is decent and i like the choice of model. But the subject takes up a large area of the entire photo, which goes against the guidelines for this challenge.
I'm afraid that you may have missed the point with this entry. This fills the frame and I've searched hard for a small item that may be intended as the subject, but with no success. Aside form this, your photo is quite soft and the child's expression is not very natural - seemingly too conscious of the camera. Light is quite flat which doesn't help either. Sorry!
Not sure the subject is a 'very small' part of the image. I don't find the pink shirt enhances the photo - almost any earth tone shade would probably be better or a blue or green or white.
I have no idea what's supposed to be minimalistic about this photograph. It meets neither the contest definition nor the classic definition. Cute kid, though the image could use some mild sharpening.
