Do you want advice on how to improve in the future or photoshop help.
If you want photoshop help, I don't think you need it! Those are bother very nice shots.
If you want advice, well others will be better suited than me, but I feel in the second shot that a bit of space on her right (our left) would have improved the shot a bit. Not much space, just a bit.
I think they are very nice shots already. I agree on the space on the left for the second shot, totally. Just so as to not have the hair so glued to the frame. Apart from that, nice work.
I am one of those freak perfectionists. Sometimes it helps but sometimes it does not.
I want to know my sharpness, skintone, contrast, crop composition, ....If all of the above look good, then I can rest my case.
I saw some images posted elsewhere, they looked mediocre. But after some of you retouched, it looks stunning.

Beautiful kids! You have great subjects to work with!
My opinion:
Looks like you used on camera flash, no? The lighting is too flat for my taste, maybe put them near a window for natural light or get the flash away from the camera. And, of course the framing on the second one.
Your little girl should be a great one to practice on !..
