first i need to say, you have beautiful hair!!!
and i think you have an oval face shape. with a really nice bone structure. natural beauty you are!
i think you would look great with a lot of hair styles.
actually i have seen a few girls with a bob and wavy hair, and some looked awesome.
have fun with getting rid of your long hair. if you are sick of it, its a good idea to get a new cut. even if your long hair is really wonderful, a shorter cut can look wonderful too
