Similar to his works on animals, Professor Au's painting of birds also carries the symbol of magnificent strength and sharpness. Take for example, the eagle in this painting, one point worth highlighting is its sharp eyes.

Its daring sharp eyes convey shocking vibrancy to absorb the attention of the viewer.

What's more, its posture of standing on one foot and looking forward with focused eyes, together with the power of water pounding against the rocks, it fully absorbs the audience with the magnificent strength and sharpness displayed.
