Note to DPC/SC: My camera's date/time is set to UTC; I had this approved by the SC when I first joined dpchallenge.
A somewhat unusual/"artistic" shot for me, and I expect the voters will slaughter me for it, but I thought I'd try.
"Just submit it."
Shot handheld; off-camera SB-800 speed light (below and left); my first shot inside a new 24" lightbox. These are the Christmas trees atop an altered art project of my wife.
Shot handheld, off-camera flash, 50mm/1.8 lens, at iso 400, 1/60 and f/22.
You've contrasted a light foreground with a dark background, but there are essentially too many mid tones in evidence to call this a high contrast picture.
