Your nose is amazing especially the tip!!!!
Definitely an angular tip is what you WANT. This is actually the reason why many ethnicities get rhino is to define the tip.
You are lucky to have it like that naturally. I've had rhinoplasty and my tip is still rather blobbish. Please please please do NOT mess that up it looks great.
Also FYI I think you are going to grow up to be absolutely STUNNING. You have great bone structure, lips, defined nose, and the whole package. You are so pretty don't change your nose
