I'm no portrait photographer, but these seem pretty nice based upon the variety of things I see here. Seem like decent lighting, too. I think there is a bit more dead space in a lot of them than I would like, but I also note a seemingly real connection between Dad and kid and they both seem pretty photogenic.
There is something a little weird about them to me, though... dunno... setting feels odd maybe? Dad in casual shorts and shirt and kid all gussied up? Something. Dunno.
Still, very nice.
I'd crop a bit and sharpen them and I'd say you have a win.
