Definatly look at your white balance. Check your camera to see what setting you were at.
Hopefully you shoot in RAW, which makes this a quick fix in most editing softwares.
As for the picture itself, it looks technically nice (other than the WB) as in exposure looks good, if maybe a bit underexposed (but that may be the WB).
The composition leaves to be desired though. With a gaze looking off camera, I think that leaving more room on the right side of the image, putting her more on the left, might improve the shot.
I also don't like her hands, both how they are positioned and mostly how you cut off the fingers on one hand. Luckily, bad hands + needing more room on the right lends itself nicely to a crop.
There really isn't that much going on in the image to make it interesting. She is a cute kid but with nothing setting a backdrop, no interesting look in her face, the photo leaves me wanting more.
But again, technically good, but work more on getting moments and interactions when doing candid photos
