My 3 years old son.
What do you think of this?

I don't like the pose, particularly with the hands off screen. It
makes me think that you had to tie him down at the wrists to get
the shot. I must admit I have a problem with croppings where it
looks like the photographer didn't properly frame the subject, and
little bits of the subject are off screen. Outside of the pose, I
do like the expression on the face.
In terms of background, you might want to consider using a
different color background, since his hair blends in with the
background on my laptop screen. I'm sure if you printed it out,
you would see different colors, but often times subtle color
variations don't show up as well on online postings, since most of
use don't use things like spyder that advertises here to color
balance the monitor.
