Which excerpt from Thomas Hardy's The Darkling Thrush most plainly expresses awe for its subject?

The lines "An aged thrush, frail, gaunt, and small, / In blast-beruffled plume" most plainly express awe for the subject, as they describe the thrush as fragile and weather-worn yet still singing with fervor and beauty. Hardy's use of imagery highlights the striking contrast between the bird's appearance and its powerful, uplifting song.
