Hands aren't particularly something you should worry about, as others said, it's more about the way you hold your hands and your wrists. However, you also have to hold them in a natural way, you aren't playing a caricature. My girlfriend is 4 inches shorter than me, and her hands are as large, if not larger than mine. She also has a noticeable adams apple, much more pronounced than anything I have is. However, she is one of the most prissy, feminine shaped and daintiest women I've ever come across. Furthermore, nobody ever notices these features on her.
