Cute kid!
There is no Exif data in the shot.. but it looks like you shot wide open? Probably 1.8 or so? Personally I like a bit more DOF (just a little). Some important areas look like they are just starting to go out of focus (teeth even)! Eyes look a little oversharpened... and shooting DOWN on a child seldom works. Much better to get down on their level! What focal length did you use? It looks like there is some perspective distortion also... Her head is huge in relation to the rest of her!
Perspective Distortion Effects Planned or Accidental
And yes, that watermark is WAY BUSY!
