Obviously I don't know you, and there is only the one photo to go by. I like the long hair as it suits you. I can't picture you with short hair.
That being said. If you want to try something short, go for it.
Tell the stylist what you basically want style wise. But you want it to accent your face. You don't want your face to take away from the style. You don't want your face looking to long or wide or whatever.
