I think your question is great for two reasons, pointing out the absence of all cultures in our field as well as the question regarding your nose. I was recently volunteering my time in Iqaluit, a First Nations City in the Arctic in Canada. In fact, I had this exact conversation with an individual up there. One point I noted is that there has never (at least to my knowledge) been a study assessing desires, interest and outcomes in the First Nations population.
Nevertheless, I believe there is hope as what really matters in the end is what you want. Based on your pictures, i get the feeling you are worried about your dorsal hump (or the "bump." This is something that is straightforward to improve. Also, the tip of your nose seems a bit wide, however its difficult with the pictures thus an "in person" assessment is needed. I say these things just to point out that there is hope and the important thing is what you want, bother personally and culturally.
Its important you are honest with your surgeon as you really need to find someone who appreciates your unique culture history and helps you look they way you expect.
As I mentioned, my advice is to find a FRCSC in Canada or a Board certified surgeon in the USA to help with this and to go over your unique circumstance in person. Hope this helps.
