Hi Straun. well let's just get my first reaction out of the way.... OH my gosh she is so beauuuuutiful!(posted 8446 days ago)ok.... now for the photograph. :o)
there's a definite blue-violet cast, especially at the bottom which bothers me because i want her surroundings to seem warm and they seem cold because of the color cast. window light? i would have done it in black n white anyway, just my personal preference though... the top part of the image is darker..... keeps it from looking high key to me. i think an important element of high key work is to have a lot of reflected light bouncing around to minimize shadows. just white foamcore boards propped up around her might do it, but i think you needed more light as well. last nit pic is that her right arm is pointing my eye right out of the image at the bottom. perhaps if you'd waited till she pulled it up in the same position as her left arm. i cropped this just across at elbow level, eliminating her arms and hands altogether, and my eye gets riveted to her beautiful face, and stays in the image.
you have a wonderful model who obviously enjoys posing for daddy, so let's see some more!
by the way, i think it's a wonderful baby portrait as is, my comments spoke mainly to your desire for that high key look. :o)
