This poem shows how physical beauty attracts us more than the inner beauty. A person is truly beautiful if there is a combination of both. But then, it is also observed that with "compassion, thoughtfulness and honesty" a person is beautiful anyway.
Thoughts-
The theme of beauty is dealt well in this poem with rhyming couplets.True beauty is not in need of make-up, posture and a cultivated charm. It can become an obsession with some, who concentrate at all hours of the day to look good.
It is a fact as the poet says that it takes a long time and experience to understand true beauty.
Imagery depicts true beauty, making it appeal to the eye.
It flows well.
