I like 3 and 4.
3 should def be your main photo, it is pretty solid.
The strong point of 4 is the smile, but try zooming in a little more, no need to show so much above you.
The idea in 1 is kind of good, the photo quality is awesome, however I don't like your pose and smile, it conveys boyish vibe. Sunglasses and bit more sassiness in the pose would make it solid.
