So unfortunately, i didn't end up getting a photo for the Oxymoron challenge. The couple ideas I had, one i didnt have time to do, and the other i missed my chance. I was gonna take a picture of the snow with the cherry blossoms out front our house but it melted by morning. Looks like Sean already beat me too it anyway ;) So anyway here's the rest of mine:

I didn't have any night shots i really liked but since i wanted to post something here is the only one that looked interesting:
Finall here is the Green one, from a flowershop in my building:
As far as touch-ups:for the B&W i chose the green channel from the full color photo as my b&w image, other than that no photoshop.
For the Night shot i cropped and rotated it a bit
For the Green I had to boost the brightness a bit because i accidently had my camera taking -1 brightness pics and didn't realize it. I also took a little bit of the yellow out.
