As a starting point I feel sympathy for this image - especially when thinking it has been made for a different motivation / reason than sharing it on the internet.
There is a nice harmony in the image, which offers a good background to focus on the person. The pose, or gesture, or attitude - as natural all this is - is again interesting, special enough to find this image interesting for many, many years to come - when knowing the child.
The person in the image comes across as a person with a character, and this is an important achievement when thinking about these images.
When looking at it without having the chance to develop a larger interest for the little child shown, than there are a few issues which could be addressed - the standard response based on "wider accepted rules".
The direct, frontal view is intensive, but is concentrating all attention towards the face, a fraction of an angle would have been inviting the eye to consume the surrounding also - understanding the image as something what is supposed to be seen as one composition - not just one part in it.
I like the low angle, but could suggest to keep the background in mind when taking the image - you might could have avoided the car with a small twist - or maybe not.
The image could have been more pleasing for the eyes of the ones not knowing this child when trying to avoid the very centered position of her in the image.
For many good reasons are the "rules of third" a great starting point to improve the quality of images - improved quality in terms of being presented in a more attractive way - which again creates interest etc.
It is of course absolute ok to also ignore such "rules", but I would suggest to do this on purpose - means knowing about - and leaving it for the sake of an more important though.

I do like this photo, it speakes to me, I find the person pictured interesting - above just being a cute little child in a nice image - and I think that you could do more images, maybe some with more feedback when maybe trying some of the known concepts first.
