Your nose can be made smaller and more in proportion to your face. It is really difficult to say exactly what I could do, but usually, I reduce the bulkiness of the nose, sometimes even build up the bridge as well as reduce the size of the nostrils. I would suggest that you send me photos. I also Skype with my overseas patients.
Obviously you need to find a PS with experience in ehtnic rhinoplasties and rhinoplasties in general and then have him take your photo digitally and then alter it with your imput till you see the simulated result that you would like to see on your face. Assuming it is realistic, then ask him how he would accomplish it. That way going into surgery both you and the surgeon will have the same final result in mind.
