hey! well, i just e-mailed you your pic with all these lines... let me know what you think of it.
I really don't think you should do anything to correct it, it isn't noticeable!!! As Melachlydaye said, you do look handsome, and as i've mentioned before, you can only tell if you have a pic facing front and you take it and draw lines on your face. On a scale to 1 to 100, i would rate you an 8... You're not PERFECTLY symmetrical, but close enough to normal symmetry in people. And really, i just CAN'T find anything wrong with your nose!! and i am looking soooo hard to find what you're talking about when you say that it scrunches, and that from one side it looks bad, etc... i just DON'T see it!! Your nose looks perfectly fine to me.
About your chin, it just seems to be off center, i don't notice one side of your face being longer or shorter, it just looks a little to one side.
And sorry, i don't notice any substancial difference between the pics you're asking about. If you were to flip them i wouldn't be able to tell your right side from your left side.
