Very compelling use of the verticals, Meg, well done. Strong perspective control and satisfying colour work. In a similar setup, I would also be tempted to (based on the assumption that the rider is available for arrangement within the frame) 1. frame the rider so that only part of the front of her is entering from the bottom left of the frame. 2. Have her coming straight at the camera and make a strong approach/depart shot. Pleasant effect.
