Elongation???

I have heard from a few sources that my drawings are elongated. I have noticed this as well when I print them that they seem tall and skinny. I was wondering if they seem that way when viewed by anyone here?

I have just had my first look at them through a different computer and boy are they different from what I see on mine. I am just trying to figure out where I have gone wrong. Even when I view them in the gallery they look normal to me, unless I am on this computer. It seems to be only the ones that I have done entirely through Photoshop.....Suggestions or imput please>>>>
