they are ok pictures of a lovely young girl, if you are looking for critique, here’s my thoughts:
love the expression in the third one.
number 1 is better in focus/sharpness.
light seems very flat in all of them, possibly due to the on camera flash and straight on / centered composition.
i find them very staged apart from the last one, i would try and capture them in a more relaxed natural way… let her play and have fun, while still interacting with her so that every now and then she’s looking at you.. don’t focus so close to her face, they remind me of passport pictures with a smile..
try and compose without centering the subject always in the centre.
