Well, this is not a wedding

I do not at all see the comparison - a wedding is at least 3 different places, so much happening, party, people, portraits, dress, etc etc etc. This is a baby and a baby can only be up and happy for a certain amount of time. When I have photographed babies, they only lasted around 1 hour actually.
The guy said, he felt he got paid to little, and since he is learning I think he would benefit with spending more time with the different poses, trying different angles to find the best one and work a little more on the PP. I think some of the images looks a little unfinished.
