is my nose bridge high or low? I come from an ethnicity known for high nose bridges. (photo)

It is difficult to fully comment as we do not see a full face photo. Your 3/4 photo does not suggest that your bridge is too high. See a surgeon for a consultation who offers computer imaging. Then, you can see what is possible based upon your anatomy. Nasal refinements can be performed while preserving your ethnic heritage.

In many cultures a masculine nose looks best when the bridge is relatively high (think Greek noses or Brad Pitt) I like to see men's noses start closer to the eyebrows and your 3/4 view looks as if your nose starts at the level of the pupils. Your front view will also improve with a graft on the bridge.
