Thanks for your question and photo.
I wouldn’t cut too much off the length as it really suits your face shape. ...More >
Having said this if you are after a bit of a change what I would suggest perhaps having a sweeping fringe/bang put in and having some framing layers around the sides to add softness around your face.
I would also introduce some more long layers throughout and have about 2-3 inches cut off the length, all this will create more body and give you the option to wear your hair curly or smooth depending on your mood.
