How much difference is normal when it comes to your hands, feet etc,
being bigger/smaller than the other one, does anyone have pictures of
this being the normal case on people.
I have found my dominant hand to be bigger than my other, it stands
out a bit more than other people who have this also.

This is indeed normal.  Most persons' dominant hand is larger and
often one foot is.  Someone recently asked a question here mentioning
a whole size difference.
Women's breasts are often not identical in size, I have read.  

If you really start inspecting yourself, you will probably find that
your eyes and ears may not be identical in size and shape.  The fact
that most of us don't hold our shoulders level is a different matter,
but it may make one arm appear longer.

The answer to a question about non-cultural perceptions of human
beauty/attractiveness pointed out that symmetry seems to be an
unconscious major factor, mentioning the supposition that this
indicates to our primeval subconsciousness better genes for breeding.

HOpe this helps  - just a free comment.

Thanks, it helps to know I'm not alone.Bye.
