Charade movie poster process

We were assigned to do a movie poster and so I chose Charade starring the fab Audrey Hepburn and the wildly handsome Cary Grant. I wanted it to be stylized but still have a retro 60's feel to it. It's the first time I've turned in an illustration assignment using illustrator.

Here is my first idea of her. I thought I would add a menacing silhouette behind her as an homage to the original poster.

So I came up with this but the silhouette isn't threatening enought and there are lots of little problems like her blending in to the shadow and the text being to bright and seperate from the image.

Here is my newer version of Charade, I want to still work on it in Photoshop, but it's what I got so far.
