Roller coaster shadows

This is a picture of a roller coaster, that I took while I was at Knotts's Berry Farm  last weekend. I like the the color of the sky a lot in this picture, how it is a blue/gray in the left hand corner and then fades a bit into a white.The state of the sky often effects our moods, I like that someone on one side of the park could be feeling one emotion and someone else can be effected differently by the same sky.My favorite part of the picture is the shadows reflected on the bottom bars of the coaster. It is something you would most likely over look if you were not paying close attention.The idea of playing with shadows in dramatic lighting is something i'm interested in.
