Photography is an art. Some people will look at art and say "Masterpiece!" and some will say "Crap" to the same piece. I see this constantly within my own work, as some people love a shot that I don't particularly like.
What I'm saying is, forget your friend. Many people will look at your work. Some will love it, and some won't. If they don't like it, they won't remember you. If they do, they'll buy your work
For instance, I can rattle off at least 10 people on flickr with outstanding photos, but I can't name 1 bad one.
