I believe 1 and 2 are soft and need selective sharpening.
Not sure of the saturation on #1's clothing, it seems to distract from the baby.
#2 seems overexposed but some do like this.
I am not fond on the processing on 3, I would like to see the original color shot .
The posing in 4 is cute but awkward.
I think its a good start and just keep practicing.:thumbup:
