Phantom photographer

I am new to photography and have only done a pictures that have caught my eye when I am out with my camera. I was asked by a friend if I would like to take some pictures at their wedding to use to build my portfolio to which I jumped at the chance. I would like to gain valuable experience in all kinds of photography and am willing to learn from other photographers and models that are willing to help. I am based in North Wales but can travel and would love to do some locations shoots and if the model has any ideas of a shoot they would like I am willing to do them to build my portfolio.
