Possibly. It depends on what type of modelling you go for. You are quite slim so go to agencies or advertising places that want slim looking models. Some want skinny some want curvy girls (as in wide hips and bosum and skinny waste) some want athletic and some want plus size.
Possibly but I suggest trying it parttime first before going professional... competition is VERRRY FIERCE I heard... everyone is good looking and the only true factor that determine success is connection.
Most models are only strikingly beautiful when they have make up on. So the standard of beauty for you, isn't impossible to reach.
You just have to be photogenic and good at posing in photos. Be aware of your body, face and limbs. You also need to have a bubbly personality and be able to easily book modeling jobs for you to be a successful one.
