weird

This is strange for me and no dont worry, i am not heading in some far out direction.
I took a photo of a girl i work with and converted it to black and white. I liked the shot but it didn't blow me away or anything. I thought it had enough potential to look at a second time and see what creative things i could do to it.
I started by duplicating my background layer and with the new layer active i went to filter - sketch - chrome. I used a detail of 0 and a smoothness of 10. I used a levels adjustment and cranked the sliders to the middle so i only had black and white tones.
I actually was going down a totally different route. I started by duplicating my blue channel as i was going to try and make a funky mask and bring parts of the original image through the chrome layer.
I thought this image i ended up with would make a cool poster if text was added.
One added note by the way: you can control how thick your black lines are by where your levels sliders end up. If they are closer to the black side or closer to the white side makes a difference.
For what i dont know.
