Lol, nice picture!
To me it looks like you have an oval face shape. If you don't want too much of a change, I'd suggest something layered. Maybe with shorter layers in front by your face... I have somewhat of an oval face shape and I've found that having shorter peices by your cheekbones look good. Maybe some bangs *shrug* or sidebangs.
When you go in to get your hair cut the stylist should be willing to work with you. I've been told that oval shaped faces can wear lots of different hairstyles well

but that might've just been something I was told and not true.
