My first event

Last weekend I had a very important event for me, it was my sister's fifteen birthday. It was very important for me because I was the photographer of the party and it was a huge responsability. I love photography that's why I accepted the challenge of taking photos for her birthday. I was very nervous but at the end i got excellent results.
