My nose looks different from different angles. When I turn to the left (1st picture), there is a bump at the top and my nose is curved. When I turn to the right (3rd picture) it looks nice and straight. Looking straight on, it goes off towards my right eye and isn't centered.
When I was much younger, I banged my nose causing it to bleed significantly. I believe this caused the bump you can see in the first picture. The bump itself is on the side of the nose which is why the appearance is different from each side.
