Good job, I like it and my first thought was crop. I'm never opposed to cropping if you can.
As far as the rash, what do you think about using a different paper? I have some Ilford warm-tone fiber and it makes any skin I've ever printed on it look really smooth and beautiful.
Bit a moot point at this stage, I already printed it, got it framed and gave it to the intended recipient who seemed quite impressed by it and didn't recognise her own baby :D
