Quoting /b/i/r/d:" critique! i shoot with a nikon d90, 50 mm lens mostly. still getting the hang of it."
As a whole - I don't think they're terrible. I like the fact you have some variety in your compositions. I think one of the main thing I see is focus issues. Not sure what kind of aperture you are normally shooting at.
#1 - The focus is completely on the headband, so I think it would be a lot better if the focus was on her little eyes/somewhere on the face.
#2 - Very cute little smile here. I feel like the backdrop is what's in focus here. And your composition is very tight. I am not sure what you're shooting with, your EXIF has been stripped.
#3 - What kind of lighting was used here? Just natural light? Flash? The comspotiion FEELS slightly awkward to me with the crop on her legs, although technically I would say it's passable since it's not right at her ankles or anything.
#4 - I like the idea here again with little brother out of focus, although the focus is on the truck and not the baby. He also looks uncomfortable since some of his face is just resting on the truck with nothing under it, and I hope someone is holding onto him outside of the frame.
#5 - I like this shot, I don't mind the outer eye being slightly out of focus. I would just like to see it warmed up and a little fill added specifically to the left side of the face. But I like the look and the composition works overall, for me.
#6 - I like this composition/point of view quite a bit. It SEEMS like maybe the focus just fell past her face to the edge of her hair, but it's hard to tell at this size, honestly, it seems like maybe the yes have been digitally sharpened? The color/processing feels maybe a bit gray for my tastes.
#7 - Good composition again here. I'd like to see a little more brightness in her face. Looks like it was probably overcast outside?
#8 - It's a cute capture. The crop is a bit tight again and I think it could use a little warmth, the colors feel a little funny to me, just a hair. The eyes are also a little dark (overcast again?).
#9 - Really like this composition. Very cute.
#10 - Not a fan of this kind of crop (square) but it's a cute shot. I think it needs some warmth though.
Hope that helps.
