It has to be in iambic pentameter and has to be in sonnet form.
(ababcdcdefefgg)

Color appears as the cold melts away,
And the bright sun smiles down on the earth.
Flowers bloom a rainbow of colors in May,
Happiness is what Spring’s warmth is worth.

Birds sing a tune and the frogs croak along,
While the bees buzz and trees sway to and fro.
Spring is what sings nature’s beautiful song.
And what makes the bubbling brooks flow.

Please review and tell me if it is a good sonnet so far or not.

THANKS!
