Details, details ... Yes there are detail issues with each of the photos.
#1 has a problem with a vertical line in the background that runs out of the head. Also has a problem with the white element on the left and also the one in the background that detract from the shot. I also find this shot a bit soft and the eyes not as sharp as they ought to be. Maybe this is due to minimul catchlights in the eyes, but I'm not sure.
#2 has white pillows in the background that clutter the image. Also I think it is too tightly cropped (head and fingers). Could also use a bit more light on the face to even out the lighting and lighten up the eyes a bit.
#3 is the best of the bunch, but is a bit flat and needs a bit of contrast adjustment in my view. The catchlights are a bit odd (did you use some sort of ring light?).
