On my way to the supermarket today, these grasses were in a field, they remind me of pampas, but apparently they are, miscanthus sacchariflorus or Amur Silver Grass. I liked how they looked with the cold afternoon winter sun behind them.
Well done with the lighting! I live taking photos of grasses like that jn the winter, but have had a hard time getting the lighting and shot to be interesting. Your composition achieves that!
