advice on removing upper grill on a 05 reg wrx. founds some clips but still won t seem to come away

 

there's the four clips at the top, they are easy enough to find and remove. It's also held in by two at the bottom. To get them out, I work one at a time with a long screw driver pushing down the clips from the top and then pulling the grill away. They are in the bottom corners.

 

thank you for advice will have a look later
