"You bet we're always ready when called upon to go
No matter whether sunshine or in rain
And a jolly crew you'll find us,
if you will come and see us
In that little red caboose behind the train
little red caboose,
little red caboose,
little red caboose behind the train... "
At least on the internet, I can sing without fear of being HEARD!
In PShop, I cropped the image to emphasize the caboose with the two railroaders, then used a copy of the blue channel to mask out the pole and wires at the top of the image.
I made a texture layer, then used it as a mask to apply some filters -- dry brush, cutout, brush strokes -- to part of the image. Then added my texture at a reduced opacity in overlay mode.
