Theres 2 clips under each headlight you probably missed. You cant get to it from the outside. Unlike civics you gotta take the bumper off by removing the bumper support. Heres how I do it..

-unplug the bumper turn signal lights
-remove screws and plugs that hold the fender well lining to the bumper
-unscrew the 1 screw in each fender well
-unclip the 2 clips underneath the car
-unscrew the 4 bolts holding the black bumper support to the car
-pull the bumper up and forward and slide out the bumper

Pretty much it, anything else I may have left out.. its been awhile since Ive taken mines off..
