Can my nasal bone between eyes narrowed or with only graft or breaking? Can I get a more defined bridge?

Thank you for the question. The result you want to achieve is possible. To narrow the nasal bridge an osteotomy surgery is required. It should include medial and lateral osteotomy to give more effective result. Your nose tip still looks bulbous so I would recommend tip revision surgery to make less bulbous and have tip defining points. 

I would recommend several aspects of the nose to be repaired: narrow the bridge between the eyes, make the tip less bulbous, and support the tip in a bit of an elevated position.This would probably require some grafting to hold the shape of the nose.
