Here's my shot at challenge 6. This is a still image that I took from video - the video that I shot was on the ferry which offered a lot of vibration. Even after a few attempts at stabilization, I was still unhappy with the results so I ended up just using a still frame instead. The color correction was applied using a tint effect in After Effects (the same affect can be applied in Premiere) where I remapped the whites to a blue-ish hue while the blacks were mapped to a beige. The tint was applied to an adjustment layer which I blended with the original image using the Hard Light blend mode.
Here is the version with the video (instead of the still frame):
