Tread very carefully here I would say. I think your profile both smiling and non smiling is very good. (You have very nice teeth, a nice nose and good skin btw) I dont think the photo shop picture looks any better (it may even look worse than you are, as Gregor said, a slight underbite look in the photoshop picture)
I would also agree that you would not benefit from a genioplasty. In short I agree with everything Gregor said.
