Wat-cha-ma-cal-it?

I was trying to get one good shot at least out of these bunch of enormous feather white grasses (they look pampas to me though) which are standing tall, beautiful--swayed by the cold gentle wind under the stunning sunset of the south. But the train was at its constant speed that I struggled to capture what I really wanted. Fortunately, here's the best one left from those endless clicks. I don't even understand what this photography like or called--wat-cha-ma-cal-it image perhaps.
