Congrats for making it to the next round!

Nice shot, but you may want to crop some off the bottom to be sure you have 50% black.

Congrats for making it to the next round, dem!

Lovely but the blacks aren't quite black

Cant make it a B&W. Against the goal.

Increase contrast & dodge the highlights on her face to make them "pop up" from the rest of your photo(after increasing contrast you might loose some of the face...)IMHO!!!
That way you'll have a fantastic low key photo.
I just tried it.
Open your photo in PS.
Image/Adjustments/Levels/Preset/Increase contrast 3
Then select the dodge tool.
Range:highlights/Exposure 55%
Done...!!!!

Congrats for making it to the next round, Artifakts!

Just amazing.

Congrats for making it to the next round, Geo!
