In a high key image like this the egrets translucent feathers look great but you have to be careful since backlighting like this will really show how well the lens designers corrected for lateral chromatic aberrations or color fringing. The Sigma sports lenses are all very highly well corrected so CAs are never an issue, even in backlit situations like this.
